The Higher The Seasonal Energy Efficiency Ratio (Seer), The Better The Air Conditioner It Will Be?

When choosing air conditioners, many customers will see a label with a SEER value. While the salesman would stress that the higher the SEER, the more energy-saving the air conditioner will be. But is the higher SEER a better option? Now we are showing you the facts behind it and helping you select the air conditioner more scientifically.

I. What is SEER?

SEER, fully named Seasonal Energy Efficiency Ratio, is used to measure the average energy efficiency level of an air conditioner in one cooling season.

Calculation formula:

SEER = Total annual cooling capacity (BTU) ÷ Total annual electricity consumption (Wh).

The higher the SEER value, the better the cooling effect of the air conditioner in the unit power consumption and the better the energy-saving performance.

SEER and electricity cost relations

II. Is a higher SEER necessarily better?

From the perspective of energy saving, it's true that higher SEER saves more electricity, but it depends on several factors:

Advantages:

Lower electricity cost

High-SEER air conditioners will consume less electricity in long periods of operation, making them suitable for regions with high temperatures or long-term usage, such as the Middle East and Southeast Asia.

More Eco-friendly

Higher energy efficiency means less emission of carbon, which applies to the policies toward environmental friendliness and energy saving in European and American regions.

Easier to pass export certification

CE, GCC, ISO, and other certificates are all included with energy efficiency estimation. Air conditioners with higher SEER will be more likely to pass the tests and acquire the market access.

Notes:

High SEER ≠ the most energy-efficient in actual use

SEER value is tested in standard working conditions, while the actual using environment, installation, and the indoor heat burden will all influence the energy-saving effect.

Higher cost on the air conditioners

High-efficiency air conditioners are normally adapted with a full DC inverter system, an excellent compressor, and a high-efficiency heat exchanger, combining to create a higher initial cost. It needs to weight the cycle of investment feedback based on the budget.

High requirements for maintenance

High-efficiency systems have high requirements for maintenance, cleaning, and installation, which are necessary to inspect regularly in the long-term use to maintain the working efficiency.

III. How to select a cost-effective air conditioner with high SEER?

Normal household users:

We recommend choosing an air conditioner with a SEER between 15 and 18, considering initial cost and energy-saving performance.

Commercial/long-term operation scenarios:

Offices, canteens, and breeding farms can choose SEER 20+ air conditioners with low operation costs, which is considerable in long-term energy savings.

Export enterprises/dealers:

It is necessary to focus on the local compulsory requirements of energy efficiency if exporting to the Middle East and Europe markets, such as SASO, SEER >= 13, EU ERP standard, etc.

It is true that SEER is the key index to weigh the energy-saving performance of air conditioners. Whether the higher SEER product is much better, it needs a comprehensive evaluation based on actual demands, operation environment, and the budget. Only by choosing a proper and suitable SEER value can we achieve energy savings, environmental friendliness, and the maximization of long-term value in a real sense.

How Mechanical Knob Thermostats Differ From Smart Programmable Controllers

How Do Mechanical Thermostats Work?

The temperature sensor in a mechanical thermostat (also known as bi-metal) is made up of two pieces of metal that are laminated together. Each type of metal has a different rate of expansion when heated or cooled, which is what controls the thermostat temperature.

Note: Mechanical thermostats operate within a temperature range and you are not setting an actual temperature.

The thermostat manufacturer calibrates the thermostats in the test lab, so the numbers on the thermostat closely match the actual temperature of the room. This means the temperature in your room will stay around your set point, but can be about five degrees above or below it at any given time.

How Do Electronic Thermostats Work?

Electronic thermostats have digital sensors to read the room temperature. They're much more accurate and responsive than mechanical thermostats, which means your room should stay within 1 degree of the temperature you set on the thermostat.

Note: In addition to increasing comfort, the smaller temperature swings of electronic thermostats can translate to energy savings.

How To Know Which Thermostat To Choose?

Even though mechanical thermostats aren't as responsive as electronic thermostats, our Vice President of Engineering says that some people want to use a thermostat like an on and off switch. In this case, mechanical thermostats are an excellent choice because they are more affordable than their electronic counterparts.

Note: Electronic thermostats aren't designed to withstand a certain amount of power or inconsistency. Power surges or "noise" on a power line could potentially fry their electronic components.

If you're still on the fence about choosing either a mechanical or electrical thermostat, check out our blog on controlling a thermostat to know which option is best suited for you.

How Does The Installation Position Affects The Cooling Performance of Air Conditioners?

When choosing air conditioners, most people are concerned about the brand, efficiency, and horsepower. They often miss a key factor, which is the installation position. In fact, even if you purchased a high-efficiency air conditioner, if the installation position is unconventional, then the cooling performance will be decreased and energy consumption will be high, or the life span will be shortened, etc. So how important is the installation position? How to choose a perfect position for installation? Here we will explain and help you pick out the best position to install your air conditioner.

I. The impact of improper indoor unit location

1. Uneven cooling, bad comfort feeling

If the air conditioner is installed on one side or locked by the furniture in the room, the cold air can not be spread evenly. This will easily lead to "one side cold, other side warm" and greatly discount the feeling of comfort.

2. Lower cooling efficiency, more energy consumption

The air conditioner starts frequently to adjust the temperature, consuming more electricity and damaging the air compressor easily. It's not cost-effective in the long run.

3. Blow directly toward human body; it triggers "air conditioner illness"

Installation at a lower position or facing the bed will make the cold air blow directly on the head or body, easily lead to "air conditioner illnesses" such as cold, headaches, muscle stiffness, etc.

The indoor unit shall be installed in the middle-upper part of the room, avoiding the positions that could blow directly on the human. The air vent is toward the open zone of the space, which is better for cold air to spread.

Air conditioner indoor unit

II. The impact of improper outdoor unit location

1. Bad radiation, lower cooling ability

If the outdoor unit is placed under direct sunlight or bad ventilation and the heat can not be radiated effectively, then the cooling efficiency will be greatly decreased.

2. More noise and vibration

Installing on window sills, corners, or weak structural areas can cause noise and vibration problems due to resonance or unstable support.

If the air conditioner is installed on window sills, corners, or weak structural areas, because of the resonance or unstable support, it will make noise and vibration problems.

3. Lifespan problem

Being long-term exposed to sunlight or heavy dust accumulation will accelerate the aging of the outdoor unit, influencing the lifespan of the whole unit.

The outdoor unit should be placed in a cool and ventilated location, such as a balcony, and keep a heat radiation area of at least 30 cm around it.

Air conditioner outdoor unit

III. Common misconceptions inventory

Misconceptions	Description
Concern on beauty rather than the air flow.	If the air conditioner is installed too high or blocked by the ceiling, cold air circulation is hard to achieve.
The outdoor unit is too close to the wall.	The space for heat dissipation is not enough, affecting the operation efficiency of the compressor.
The indoor unit faces the bed.	The cold air blows directly to the human body, influencing our health.
The distance between indoor and outdoor units is too long.	This will lead to too long a connecting pipe, increasing the energy consumption and installation cost.

IV. Advice for the best installation position.

Bedroom: It should be installed in the upper position of the side wall, avoiding facing the bed.
Living room: It's better to choose the position near the center of the ceiling or the unblocked wall.
Office: Keep it away from the workplace, ensuring the cold air is dispersed in the activity area.
Child's room: Avoid direct blowing and concern yourself with the adjustable wind direction.

V. Reasonable installation consumes half the efforts

Whether your home air conditioner works well or not, the installation position determines. Proper installation can not only improve cooling efficiency and energy-saving effects but also extend the lifespan and secure family health. As for an air conditioner, 30% is based on the quality and 70% is on the installation. Please refer to the professional guidance before installation, or give this job to the servicemen.

Do you know about Plastic tube packaging?

In the $180B global cosmetics market, customizable tubes dominate 67% of skincare packaging.Cosmetic tubes are widely used in cleansers, eye creams, primers, sunscreens and other products due to their lightness, good sealing and portability. This article will give you a comprehensive understanding of tube packaging from three aspects: the manufacturing process of tubes, surface treatment technology and common types of matching caps.

Manufacturing Process of Skin Care Tubes

Skin care tubes are usually made of PE (polyethylene) plastic, aluminum foil, plastic film and other materials.They are made into sheets by co-extrusion and compounding, and then pressed into tubular containers by a special tube making machine. The production process of tubes mainly includes: extrusion molding → cutting → printing → sealing → capping. Each step needs to be precisely controlled to ensure aesthetics and sealing. According to product type and usage requirements, they can be divided into single-layer tubes, multi-layer co-extrusion tubes and aluminum-plastic composite tubes:

Tube Surface Decoration

The printing color should be within the specified tube body range, the overprint position should be accurate, the deviation should be within 0.2mm, and the font should be complete and clear. In order to enhance brand recognition and shelf appeal, hoses are often combined with different surface decoration processes. The following are several mainstream technologies:

1. Silk Screen Printing

Suitable for small batches and multi-color customization, with thick ink and strong feel. Like the printing method of plastic bottles and glass bottles, color registration is required.

2. Offset Printing

High color reproduction, suitable for large-scale printing, mostly used in basic daily chemical lines. Similar to paper printing, large color blocks and multi-color printing are possible. Offset printing is often used for hose surface treatment. Most of the inks used are UV-dried, requiring strong ink adhesion and resistance to discoloration.

3. Hot Stamping

Highlight the logo or pattern, enhance the product texture, often used in high-end skin care series.

4. UV Printing/Varnish (UV Coating)

Partial high gloss or matte treatment makes the product visually more layered. It can be UV, matte and glossy. Although the matte surface treatment is elegant, it is easy to get dirty and leave fingerprints.

5. Pearl/Gradient Coating (Pearl/Gradient Coating)

Create a visually attractive metal or gradient effect to enhance the brand's sense of luxury.

Tube Caps Options

1. Flip-top Cap

Easy to operate, suitable for daily cleansing and shampooing products.

2. Screw Cap

Stronger sealing performance, commonly used in eye cream and sunscreen products.

3. Pump Head

Improve the convenience of use, commonly used in hand sanitizer or lotion hoses.

4. Nozzle Tip

Precisely control the amount, suitable for segmented care products such as eye cream and acne cream.

5. Metal Roller Ball

Add massage function, used for eye care or anti-wrinkle essence hoses.

plastic soft tube

Why choose hose as skin care product packaging?

Lightweight and easy to carry: suitable for travel and daily use; durable, recyclable, easy to squeeze;

Good sealing: effectively prevents content contamination and oxidation;

Strong customization: color, printing and cover type can be flexibly customized;

High cost performance: compared with glass bottles and vacuum bottles, it is suitable for low-end and mid-range product launches.

R290 has a GWP of 3, which is almost negligible.

2. ODP value: both have 0 ODP

Both refrigerants have no impact on the ozone layer (ODP=0); they totally meet the requirements of the Montreal Protocol.

III. Energy efficiency and performance

R32 and R290 have outstanding thermodynamic performance, but there are slight difference

Assessment dimensions	R32	R290
Cooling ability	high	higher than R32
Energy efficiency ratio	higher (10% better than R410A)	more higher (5-10% better than R32)
Air compressing efficiency	high	very high

In a word, R290 is better than R32 in heating exchange ratio and energy efficiency ratio.

IV. Safety and applicable range

1. Clear difference in flammability.

R32: A2L class, a bit flammable, higher safety level. It is suitable for home air conditioner promotion.
R290: A3 class, very flammable; it highly requests safety in installation and maintenance. And the risk of fire disaster exists.

2. Legal restrictions and applications

Due to its high flammability, the R290 air conditioner is now limited in applications in global countries, which are only allowed to apply it under certain capacities. (For example, China standards limit the charging weight of 150g, while the Europe is 290g.)
In large or enclosed spaces, it is normally prohibited to use R290.

V. Marketing trends and policy orientation

R32

It is widely adapted by international trending brands, such as Daikin, Gree, Midea, Mitsubishi, etc.
As a transitional refrigerant with environmental friendliness, it complies with the environmental protection policies in different countries. And the technology is mature, and the supply chain is stable.
It is suitable for the exporting of major household and commercial air conditioners.

R290

It is more and more preferred by small cooling devices, such as refrigerators and portable air conditioners.
Europe and other regions promote it on a large scale, but it is still limited due to its flammability and charging weight.
It requires a higher standard of the manufacturers and service providers on safety design and maintenance capability.

VI. Which one is the most eco-friendly option?

Comparison	R32	R290
GWP value	medium (675)	low (3)
ODP value	0	0
Energy efficiency performance	better	much better
Safety	high (controllable)	high flammability with risk
Application maturity	mature, widely used	not so mature, more limitations
Cost and supply chain	mature and stable	low cost, high requirements on storage, transportation and supervision

R32 is the most balanced refrigerant regarding comprehensive performance, environmental friendliness, and safety. It is applicable for many mainstream air conditioners.
R290 is more eco-friendly but more flammable, suitable for small, specified-capacity equipment.

Driven by the environmental protection trend and the governmental policy pressure dually, air conditioning refrigerant is now undergoing a green conversion.
