Add refrigerant in air conditioners transfer machine, as long as the control operating specifications do well Xuzhou boot after running refrigeration air conditioning repair parts, without adding refrigerant. But for the use of micro-leakage or shift due to slow movement when emptying the refrigerant will trace reduce air conditioning repair, or due to longer pipeline relocation and other factors, the air conditioner in the running for some time can not meet the normal operation of the four a condition that the pressure is lower than 4.9kg / (mm) 2 pipe frosting; Current reduction; the air temperature inside the machine does not conform to come, it would have to replenish the refrigerant. Air cleaning, the importance of maintenance: The purpose of the system is that the air conditioning maintenance services: In order to give customers more effectively and more comfortable to use the company's air-conditioning equipment, we recommend regular maintenance contracts entered into by the customer is responsible for the implementation of our regular maintenance work. Regular maintenance can reduce air-conditioning number of failures, and reduce maintenance costs. Can really grasp the machine performance, fault and electricity can be saved. The machine will not affect the production process stops unexpectedly. Prior failure by maintenance checks to prevent unexpected failure occurs. 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 to Xuzhou Hitachi central air conditioning repair, 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 Xuzhou central air conditioning repair phone, 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 CFC issue has been very clear, 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 Xuzhou Hisense air conditioning repair service _ _ from Xuzhou Shenger Da Sheng Erda refrigeration Refrigeration Electrical Services Limited.
