Types Of Two-Temperature Valves
Two temperatures, valves sometimes referred to as the constant pressure, pressure valve or a valve gearbox. They are also used to provide a constant low pressure side. The valves have a bellows or diaphragm, needle, and location. They placed so bellows operated pressure in warm evaporator.
As pumps, compressor low side down to the desired pressure bellows off valve. This action stops the pressure in the warm evaporators go below the required pressure. Pressure in the evaporator accumulated from the evaporation of the coolant. Bellows then opens the valve, passing vapor in the compressor.
The pressure on the surface of the liquid refrigerant determines the temperature at which it will evaporate. In sucdon line valve controls the temperature of the evaporator that the line is attached. This is true even when the compressor sucdon pressure significantly lower the pressure in the evaporator.
Two main types of two-temperature valves:
- Working under pressure.
- Metering.
- Instantaneous.
- Temperature acted.
- Sensing bulb and furs.
- Thermostat and a solenoid.
