Heat energy air conditioner with heat recycling function

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...

Problems solved by technology

There are a lot of heat energy in nature, such as solar energy, geothermal energy, etc. In addition, a lot of industrial waste heat and automobile waste heat are discharged into the air, which not only causes waste of energy, but also pollutes the environment

The use of this part of heat energy is currently limited to the use of medium and high temperature heat sources to generate electricity. The limitation of this approach is that a large number of low temperature heat sources (50°C-150°C) have not been effectively utilized, and the use of the generated electricity needs to be considered , grid-connected transmission and distribution and other issues
