Web27 de abr. de 2024 · Thermostatic Expansion Valves. Thermostatic expansion valves (TXVs) work as a type of throttling device and are one of the four essential components in a refrigeration cycle, along with evaporators, compressors, and condensers. As with other throttling devices, TXVs cause the refrigerant to expand as it flows, reducing the pressure.

Web29 de ago. de 2024 · The expansion valve senses the drop in pressure and allows hot high pressure refrigerant to flow into the evaporator through the valve until the pressure in the evaporator recovers. When the refrigerant encounters the low pressure two things happen. First, some of the refrigerant evaporates. Web8 de ago. de 2024 · The thermal expansion valve modifies the refrigerant flow into the evaporator. This enables a quick reaction to changes in how much heat your electrical equipment dissipates. Any changes in the enclosure's temperature will be fixed right away. The evaporator can function while cooling thanks to thermal expansion valves.

WebAs the temperature and pressure reaches its maximum, the diaphragm flexes against an air cushion to allow for increased water expansion, because unlike water, air is compressible. When the system is opened again or the water cools, water leaves the tank and returns to the system. Control Thermal Expansion in Potable Water Heating Systems A thermal expansion valve is a key element to a heat pump; this is the cycle that makes air conditioning, or air cooling, possible.
