A thermal expansion valve is a key element to a heat pump; this is the cycle that makes air conditioning, or air cooling, possible. A basic refrigeration cycle consists of four major elements: a compressor, a condenser, a metering device and an evaporator. As a refrigerant passes through a circuit containing these four elements, air ...
Wax thermostatic elements transform heat energy into mechanical energy using the thermal expansion of waxes when they melt. This wax motor principle also finds applications besides engine cooling systems, including heating system thermostatic radiator valves, plumbing, industrial, and agriculture.
Vapor-compression refrigeration [6] For comparison, a simple stylized diagram of a heat pump's vapor-compression refrigeration cycle: 1) condenser, 2) expansion valve, 3) evaporator, 4) compressor (Note that this diagram is flipped vertically and horizontally compared to the previous one) [7] Temperature–entropy diagram of the vapor-compression cycle.
All such systems have four components: a compressor, a condenser, a metering device or thermal expansion valve (also called a throttle valve), and an evaporator. Circulating refrigerant enters the compressor in the thermodynamic state known as a saturated vapor [ 2 ] and is compressed to a higher pressure, resulting in a higher temperature as well.
An expansion valve is a valve used for different purposes: Steam engines ... Thermal expansion valve, a component in refrigeration and air conditioning systems
Thermal expansion valve; Sometimes in a refrigerator several loads are varied. Refrigerators used to function at different loads operated under different condition of temperatures and pressures. There may be arrangements possible for multi evaporators on the basis of single or multi compressors.
"The 50.1 level is the smallest possible expansion for the PMI but nonetheless bucks expectations for continued contraction," said Lynn Song, chief economist, Greater China, at ING.
