Abstract

The invention discloses a heat energy air conditioner with heat recycling function, which comprises a compressor, an outdoor heat exchanger, an indoor heat exchanger, a four-way valve, an outdoor expansion valve and an indoor expansion valve. The compressor is driven by a turbine; the turbine is connected to a set of power devices based on organic rankine cycle; and the power device comprises an evaporator, the turbine, a condenser and a circulating pump. The heat energy air conditioner is provided with a plate heat exchanger which enables a refrigerant on a compressor suction side to exchange heat with exhaust steam of the power device; the heat energy air conditioner also comprises a three-way valve (V1) and a three-way valve (V2); the three-way valve (V1) has a first opening for introducing the exhaust steam into the condenser and a second opening for introducing the exhaust steam into the plate heat exchanger; and the three-way valve (V2) has a first opening for introducing the exhaust steam into the condenser and the second opening for introducing the exhaust steam into the outdoor heat exchanger. By the invention, the heat of the exhaust steam of the turbine can be effectively recycled.

Description

technical field

[0001] The invention relates to an air conditioning device, in particular to an air conditioning device which utilizes natural low-temperature heat sources or industrial waste heat, waste heat and other heat sources to drive a compressor to run. Background technique

[0002] In the new era of China's energy transformation, people are worried about issues such as environmental protection, energy shortages, power shortages, the security of national energy strategies, and the economics of energy utilization. The air conditioner is undoubtedly a large energy user, and most of the air conditioners on the market currently rely on electricity to drive the compressor to run. There are also some air conditioners driven by heat energy, for example, the GHP gas heat pump air conditioner currently on the market uses a gas engine to drive a compressor equipped with an outdoor unit. There are a lot of heat energy in nature, such as solar energy, geothermal energy, etc. In...

Examples

Embodiment Construction

[0015] Such as figure 1 The shown air conditioning system has an outdoor unit 1 , an indoor unit 2 and a control device 3 . The outdoor unit 1 is equipped with a compressor 11, a liquid accumulator 12 and a plate heat exchanger 14 are arranged on the suction side of the compressor 11, and a four-way valve 13 is arranged on the exhaust side. An outdoor heat exchanger 14 and an outdoor expansion valve 15 are arranged in sequence, and a bypass 17 is provided on the expansion valve 15 . An outdoor fan 18 is arranged adjacent to the outdoor heat exchanger 14 . In addition, the compressor 11 and the power unit 4 may be fully enclosed, semi-closed or initially connected. The indoor unit 2 includes an indoor heat exchanger 21 and an indoor expansion valve 23 , and an indoor fan 22 is disposed adjacent to the indoor heat exchanger 21 .

[0016] The four-way valve 13 is switched by the control device 3 to set the air conditioner to the cooling operation or the heating operation. Whe...
