What's the matter with the air conditioner cooling and not heating? How to buy refrigeration and air conditioning?
[Abstract] This way, whether it is in winter or summer, it can be used in the past, but many people have found that the cooling effect of the current air conditioner is better, but the heating effect is indeed poor, so what about the air conditioner cooling without heating? People should master this, and they should also know how to choose refrigeration and air conditioning.
People now choose air conditioners. Generally, they choose air conditioners that can cool and eat heat. This way, whether it is in winter or summer, they can be used in the past. However, many people find that the cooling effect of current air conditioners is better, but The heating effect is indeed relatively poor, so people should know how to refrigerate the air conditioner without heating, and they should also know how to buy refrigeration and air conditioners.
What's the matter with the air conditioner cooling and not heating?
1. Generally include cold source/heat source equipment, cold and heat medium transmission and distribution system, terminal equipment and other auxiliary equipment. It mainly includes water pumps, fans and pipeline systems. The terminal device is responsible for using the cold and heat from the transmission and distribution to specifically process the air and temperature, so that the air parameters of the target environment meet the requirements.
2. First of all, make sure your air conditioner is dual-system (cooling/heating). The mode setting should be correct, and it should be noted that it will not heat in summer or when the ambient temperature is higher than the set temperature (that is, the heating mode can only be operated in winter). The compressor sucks in the lower pressure from the evaporator The working fluid steam is sent to the condenser after the pressure is increased.
3. It is condensed into a liquid with a higher pressure in the condenser. After being throttled by a throttle valve, it becomes a liquid with a lower pressure and then sent to the evaporator, where it absorbs heat and evaporates to become a steam with a lower pressure. Thus completing the refrigeration cycle. If the air conditioner is dual-system and the settings are correct, it means that the four-way reversing valve has a problem if it can be cooled or heated. Then, find professional maintenance personnel to repair or replace it. The air conditioner is the air conditioner (AirConditioner).
4.It refers to the process of using artificial means to adjust and control the temperature, humidity, cleanliness, speed and other parameters of the ambient air in the building/structure.
How to buy refrigeration and air conditioning?
1. When buying an air conditioner, the noise level is also a point to pay attention to. Refers to the noise generated when the air conditioner is running, mainly produced by the internal evaporator and the external condenser.
2. According to national regulations, the outdoor unit shall not exceed 55 decibels; the noise of the indoor unit of the split air conditioner of 2500W～4500W shall not exceed 48 decibels, and the outdoor unit shall not exceed 58 decibels. The noise of the air conditioner indoor unit with a cooling capacity below 2000W should not be greater than 45 decibels. When purchasing, it depends on whether the noise level of the product meets the standard, and the noise value is smaller.
3. National standards stipulate that the actual cooling (heat) capacity of air conditioners should not be less than 95% of the rated cooling (heat) capacity. This key indicator of the air conditioner must be clearly seen when purchasing. When purchasing, you must look at the cooling (heating) capacity of the air conditioner. The heat generated from a confined space per unit time when the air conditioner is operating, the legal unit of measurement is W (watts).
4. The energy efficiency ratio of air conditioners is also an important point when purchasing. Refers to the ratio of the cooling capacity to the cooling power when the air conditioner is in cooling operation, in W.
5. According to national standards, the national fixed-speed air-conditioning energy efficiency ratio of 3.2-3.6 is divided into three levels, and the first level is very good. The standard value of energy efficiency ratio of 2500W air conditioner is 2.65; the standard value of energy efficiency ratio of 2500W～4500W air conditioner is 2.70. The greater the energy efficiency ratio, the better.
What's the matter with the air conditioner cooling and not heating? After reading the introduction, maybe you should already understand it. After such a situation, people should find professional personnel to carry out maintenance, so that you can rest assured. In addition, you should also understand the skills of refrigeration and air-conditioning. After completing these skills, when making a choice, the quality can be better guaranteed and people can use it better.
