Abstract

The invention provides an open type both-way thermodynamic cycle and a first-kind heat drive compression type heat pump, and belongs to the technical field of power, refrigerating and heat pumps. The open type both-way thermodynamic cycle is formed through the heated medium pressure decreasing process 12 starting from the intermediate temperature, the heat absorbing process 23 starting from a low temperature heat source, the pressure increasing process 34 starting from the low temperature, the heat absorbing process 45 starting from a high-temperature heat source and the pressure decreasing process 56 starting from the high temperature. An outer portion is provided with a heated source medium channel to communicate with an expansion machine, and the expansion machine is further provided with a heated medium channel to communicate with a compressor through a low-temperature heat exchanger. The compressor is further provided with a heated medium channel to communicate with a second expansion machine through a high-temperature heat exchanger. The second expansion machine is further provided with a heated medium channel to communicate with the outer portion. The low-temperature heat exchanger is further provided with a low-temperature heat medium channel to communicate with the outer portion. The high-temperature heat exchanger is further provided with a high-temperature heat medium channel to communicate with the outer portion. The expansion machine and the second expansion machine are connected with the compressor and transmit power. Accordingly, the first-kind heat drive compression type heat pump is formed.

Description

Technical field:

[0001] The invention belongs to the technical field of power, refrigeration and heat pump. Background technique:

[0002] Cold demand, heat demand and power demand are common in human life and production; in reality, people often need to use high-temperature heat energy to achieve cooling, heating or conversion into power, and also need to use power for cooling or use power combined Low temperature thermal energy for heating. In the process of achieving the above goals, there will be many considerations or constraints, including the type, grade and quantity of energy, the type, grade and quantity of user needs, ambient temperature, type of working medium, equipment flow, structure and Manufacturing costs and more.

[0003] Thermal energy (temperature difference) utilization technology represented by absorption heat pump technology utilizes high temperature heat load to drive heat supply or cooling; big limit. Compression heat pump technology, which utili...
