GAS HEAT PUMP PLANT Russian patent published in 2015 - IPC F24D5/12 

FIELD: power industry.

SUBSTANCE: gas heat pump plant includes a compressor, a gas-liquid heat exchanger interconnected at the inlet as to cooled gas to the outlet of the compressor as to gas, a turbine interconnected at the inlet as to gas to the outlet of the gas-liquid heat exchanger as to gas, a drive unit and an intermediate gas cooler. The compressor is of a two-shaft type and consists of low and high pressure compressors interconnected with each other in a gas flow direction through a circuit of an intermediate gas cooler as to gas, the gas-liquid heat exchanger and the intermediate gas cooler are connected as to the cooling heat carrier circuit to a heating circuit of heat carrier of a heat consumer, the low pressure compressor is installed on the shaft of the drive unit and interconnected at the inlet as to gas to a cooled gas source, the high pressure compressor is installed on one shaft with a turbine equipped with a moisture removal system. Turbine 3 at the outlet as to gas is interconnected either with atmosphere or with the cooled gas consumer, or the gas heat pump plant includes a low pressure turbine installed on one shaft with low pressure compressor 6, which is equipped with the moisture removal system and interconnected at the outlet as to gas with atmosphere and/or the cooled gas consumer, and the turbine at the outlet as to gas is interconnected with the low pressure turbine inlet as to gas.

EFFECT: increasing efficiency of conversion of mechanical energy to thermal energy; reducing metal consumption of the device.
