What is the enthalpy difference laboratory for bus air conditioners
KingClima Bus Air Conditioning
has built a modern air conditioning test center for passenger buss in China with reference to international advanced standards. The enthalpy difference laboratory for bus air conditioners
is one of the laboratories.
The test device of bus air conditioning
system is applicable to the product test of overhead bus air conditioner, built-in unit, independent unit, overhead bus air conditioner with defroster/single cooler, integrated overhead bus air conditioner (glycol/water system integrated with the whole air conditioner) with R410A/R407C/R134a/R1234yf/R32/R744 as the refrigerating agent. It can test and study the cooling and heating performance of the vehicle air conditioning system, the performance of the cooling components and the performance of the fan. It can be used as a verification device for the performance of vehicle air conditioners, and also provide testing means for the development and optimization of air conditioning systems.
Air conditioning solutions for buses compressor is driven by the engine rotation. The high-temperature, high-pressure refrigerant vapor discharged from the compressor enters the vehicle air conditioner condenser through a high-pressure hose. Since the temperature of high temperature and high pressure refrigerant vapor is higher than that of the air outside the vehicle, the heat of the refrigerant vapor in the condenser is taken away by the air outside the vehicle with the help of the condenser fan, so that the high temperature and high pressure refrigerant vapor condenses into a high pressure liquid with higher temperature, which flows into the liquid storage dryer through the high pressure hose and flows through the expansion valve after drying and filtering. Under the throttling effect of the expansion valve, the refrigerant becomes low temperature, low pressure liquid and enters the evaporator of the bus air conditioner, vaporizes under constant pressure, and absorbs the heat in the air outside the evaporator tube, so that the temperature of the air circulating in the bus through the evaporator decreases and becomes cold air, which is sent into the bus through the evaporator fan to reduce the air temperature in the bus. After vaporization of refrigerant vapor, compressed by the compressor inhalation, and become high temperature, high pressure refrigerant gas, through the high-pressure hose pressed into the bus air conditioning condenser, completing a refrigeration cycle of the bus air conditioning. This cycle is busried out again and again, so that the temperature inside the bus can be maintained in a comfortable state.
