refrigeration unit bus honeywell expansion valve for Chinese Bus

                                                                TMXR134a Honeywell Expansion Valve         Place of original: Germany   Expansion Valves are used to expand liquid refrigerant from a higher pressure and a higher temperature to a lower pressure and a lower temperature. As a controller for superheat, Expansion Valves control the refrigerant mass flow depending on evaporating pressure and temperature at the outlet of the evaporator. They adjust the quantity of the injected refrigerant exactly and guarantee an economic function by optimal use of the evaporator surface.   Honeywell Expansion Valve pictures    refrigeration unit bus honeywell expansion valve for Chinese Bus   Honeywell Expansion Valve Specifications   Honeywell expansion valve, Honeywell Brand Expansion Valve For Compresso , Honeywell expansion valve for refrigeration 1.

Method and steps: 1) Confirm refrigerant type 2) Confirm the range of evaporation temperature 3) Cooling capacity. 4) Pressure difference between the import and export of thermal expansion valve. 5) Balance way of internal or external pressure. 6) Connector size   Frame pictures of Honeywell TMX:   refrigeration unit bus honeywell expansion valve for Chinese Bus   What will happen if expansion valve fails to match system?   If don't match, it will make refrigerant system flow uneven, also lead to uneven of cooling capacity of thermal expansion valve. When refrigerant amount is too small, lead to make evaporator liquid supply shortage, generating excessive heat, and adversely affect system performance. When refrigeration amount is excessive, causing the shock, the intermittent nature of evaporator liquid supply excess, resulting in sharp fluctuations, sometimes maybe the compressor suction pressure liquid refrigerant enter compressor.   Full package pictures:     refrigeration unit bus honeywell expansion valve for Chinese Bus   You may interested other necessary AC parts, such as compressor ,Clutch,Generator,Refrigerant.     Attention:compressor has special requirement for the refrigerant, which important to keep compressor in long lifetime.
