FRQ -  How to Maintain the New Energy Bus Air Conditioning

Problem 1 - All-electric bus Air conditioning with a poor refrigeration:

If bus air conditioner have a poor refrigeration, please to draw out the refrigerant from the bus air conditioning system and maintain a negative pressure of 1 bar. Please watting for 24 hours to see if the air pressure in the bus air conditoning system is maintained at about -1 bar. If the air pressure rises significantly, there is a leak in the bus air conditioning system and further disassembly inspections are required. But if the bus air conditioning system does not leak, then we can add the appropriate amount of refrigerant according to the vehicle model.

Question 2 - The All-electric bus air conditioner is not cooling at all:

In this case, please replacing the compressor is the key task. Replacing the compressor requires first evacuating the air conditioning system refrigerant and then replacing the compressor. After replacing the compressor, it is also necessary to check the All-electric bus air-conditioning system tightness and fill the refrigerant.

Kingclima Industry as the leading manufacturer and supplier of All-electric bus air conditioners in China always keep our mind to market’s needs and comfortable driving environment. KC-ES full electric bus air conditioners are our first new energy bus HVAC to the bus world. At the same time, equip with it, we also considered the customer’s demands to bus air conditioning compressor parts --- KC-EVS series electric ac compressor for bus

Problem 3 - Unknown gas emerges from the air outlet of All-electric bus air conditioner:

This happens because the evaporator inside the center console has leaked and can only replace the bus air conditioner evaporator inside the center console.

Question 4 - All-electric bus Air conditioning abnormal sound

Abnormal sounds in the bus air conditioning system and abnormal noises in the coach air conditioning system. Please don't worry, the internal noise is generally the presence of air or moisture in the system refrigerant. The external noise is generally the abnormal noise of the bus air conditioner compressor, and the compressor can be replaced.
