What it needs to add refrigerant air conditioning does what it needs to add refrigerant air conditioning it? Some people think that the difference is the need for air conditioning and refrigeration effect to add refrigerant, in fact, not the case, air conditioning and refrigeration effect is not good, there are many cases, such as the four-way valve string gas, compressor leak, capillary blockage, etc. are possible, The following specific analysis of air conditioning not cooling: air conditioning refrigeration case there are many Xuzhou air conditioning maintenance, there are three situations: First, the voltage is too low, can not supply the air conditioning running voltage; the second is the air conditioning unit environment is poor, resulting in blockage of ventilation outside the machine poor; third is the lack of fluoride. "The first two cases occur frequently, and air conditioning because of the lack of fluoride is not really the case less cooling." Wang said, residents of the home's air conditioner is not cooling, first find the first two reasons, and often clean air filter. "If there is frost on the straw air conditioning unit, it is likely to be true lack of fluoride;. If you are unsure, ask a professional repairman detection measurement tools," Wang said. What is the definition of a refrigerant refrigerant Webster dictionary as "used in the refrigeration cycle or a substance like ice for direct cooling." HVAC industry will lay refrigerant may be described as some kind of fluid used in air conditioners. Many HVAC industry insiders will immediately think of CFC group substances (chlorofluorocarbons). These definitions are correct, but the refrigerant is more extensive than those substances. Water is the refrigerant used in the absorption chiller. Carbon dioxide (CO2) and ammonia (NH3) as a "natural" refrigerant known. Combustible substances such as propane and isobutane are also used as a refrigerant. For halogenated substances such as CFC, HCFC and HFC family matter, it is widely welcomed by the refrigerant. ASHRAE Standard 34 "refrigerant Designation and Safety Classification" lists more than 100 kinds of refrigerants, although many of them are not used in conventional commercial HVAC. The refrigerant is a chemical substance. Some substances are considered refrigerants (eg R-141b), in fact it is widely used in applications such as blowing agents, in fact, rarely used for cooling applications. CFC refrigerants once thought to be safe in humans and the planet, but in the mid-1980s it was discovered, is severely damaging the Earth's ecology. In the design of the building, the refrigerant from the once rarely discussed, suddenly became a major consideration for designers. When the air conditioning HVAC equipment manufacturers to add fluoride refrigerants as an important market selling point, mostly public that goes rational po po said. This makes the equipment procurement decision-makers often at a loss. Although the issue has been very clear CFC air conditioning, but there are many issues that need explanation. Beijing Jia-dimensional refrigeration hope to provide a detailed knowledge of the refrigerant, the refrigerant to affect our business and personal lives to strengthen understanding of the home air conditioning use, whether the user is aware of the problem a lot of air conditioning wind set? Set the air conditioning airflow is blown up or down or horizontally blowing blow then? For this problem, Jinan conditioning repair has held its own point of view: Summer winds should hit the top of Xuzhou air conditioning maintenance and fluoride, because cold air than the major, will go down from. Hot start to the winter, we should hit below the wind, hot air is lighter, will go up from the bottom, the entire room will be warm. Winter air temperature is critical, then the air conditioning and heating also pay attention to some small tips. First of all, a reasonable set of energy-saving air-conditioning temperature helps: Generally located at the lower heating 2 ℃, although the body does not feel very obvious, but the air conditioning installation for Xuzhou wedding dresses, can save an average of nearly 10% of the energy . Secondly, we must pay attention to adjust the air conditioning wind speed, wind direction: the just-conditioning, wind speed can be set to high wind speed, air and room air conditioner to accelerate the process of heat exchange, when close to the set temperature, wind speed can be set to low speed, this For can save some energy. Vary the proportion of hot and cold air, so it is best to let the wind down during the heating air conditioning in order to improve the exchange of hot and cold air, to save battery power. In addition, the doors and windows closed when the air conditioning, a long time can cause indoor oxygen, bacteria, viruses, also took the opportunity to accumulate a lot. Therefore, we advise you to Jinan air conditioning repair air conditioning more than two hours should be stopped and ventilation window.
