A thermal expansion valve (42) is positioned between the first heat exchanger (34) and the second heat exchanger (52).

Exhaust heat energy converts the fluid (27) from the liquid state into the gaseous state (39) for transfer into a heat expander (50) situated downstream of the first heat exchanger (24).

The exhaust gas from the expander may optionally heat a second heat load.

The expansion engine concerts the thermal energy output from the burner to mechanical energy output.

The present invention discloses an automatic self-adjusting thermally powered expansion valve (22, 230) for controlling the flow of refrigerant to an evaporator (20) of a refrigeration system.

The invention relates to a variable rod-in-tube pressure reducer with thermal and safety relief valve device.

A heat pump includes a compressor 1, a condenser 2, an expansion valve 3, an evaporator 4 and a heat exchanger 6a.

The expander is a volumetric expander.

The heat exchanger 6a is located immediately downstream of the expansion valve 3 and upstream of the evaporator 4.

An air conditioning apparatus including a compressor, an outdoor heat exchanger, an indoor heat exchanger, and an expansion valve to depressurize a refrigerant.

The refrigerant circuit has a compression mechanism having an adjustable operating capacity, a heat source heat exchanger, an expansion mechanism, and a utilization heat exchanger.

A heat pump system includes a compressor, a heat rejecting heat exchanger, an expansion device, and a heat accepting heat exchanger.

The refrigerant circuit (10) includes a compressor (14), a first heat exchanger (16), an expansion device (18), a second heat exchanger (20) and an additional heat exchanger (22) connected in series and forming a loop.

The thermal type valve is widely used for automobile air conditioning.

A thermal expansion valve (42) is positioned between the first heat exchanger (34) and the second heat exchanger (52).
