Installing Expansion Valves
Thermal expansion valves he must properly installed to ensure their proper functioning and improve the capacity and efficiency of the system. For best performance, TXV without a distributor must be installed as close as possible to the evaporator as possible. Expansion valves, using distributors do not have restrictions on the distance between the evaporator and the expansion valve. In addition to the collector type distributor, as the refrigerant distributor is used, TXV should be installed as close as possible to the distributor as possible.
There is a sufficient amount of liquid in a liquid-charged expansion valve to make sure that the control includes needle pressure sensing bulb under all operating conditions. Therefore, the liquid-charged TXV can be installed in any position, with a thermostatic element authorities or head oriented upwards, downwards or sideways. The valve can be located inside or outside the refrigeration space, because there is no relative temperature requirements concerning her body and feeling lamp. However, the gas valve must be installed with a thermostatic element be head and his body valve is where it always will be warmer dian sensing bulb.
