Embodiment Construction
[0054] The first thing to explain is that in the expression of the structure and process, it will not be repeated if it is not necessary; the obvious process will not be expressed. The present invention will be described in detail below in conjunction with the accompanying drawings and examples.
[0055] figure 1 The third type of thermally driven compression heat pump shown is implemented as follows:
[0056] (1) Structurally, it is mainly composed of a compressor, a second compressor, an expander, a second expander, a third expander, a high-temperature heat exchanger, a heater, a cooler and a low-temperature heat exchanger; Machine 1 has a circulating working medium channel that communicates with expander 3 through high-temperature heat exchanger 6, and expander 3 also has a circulating working medium channel that communicates with second expander 4 through heater 7, and second expander 4 also has a circulating process The medium passage communicates with the cooler 8, the...

The invention provides a third-kind heat driving compression heat pump, and belongs to the technical fields of power, refrigeration and heat pumps. A circulating working medium of a compressor is communicated with an expansion machine through a high temperature heat exchanger, and a circulating working medium channel of the expansion machine is communicated with a second expansion machine through a heat supplier. A circulating working medium channel of the second expansion machine is communicated with a cooler, a circulating working medium channel of a third expansion machine is communicated with the cooler, and a circulating working medium channel of the cooler is communicated with a second compressor. A circulating working medium channel of the second compressor passes through a low temperature heat exchanger and then is communicated with the compressor and the third expansion machine, a high temperature hot medium channel of the high temperature heat exchanger is communicated with the outside, and a heated medium channel of the heat supplier is communicated with the outside. A cooling medium channel of the cooler is communicated with the outside, and a low temperature heat medium channel of the low temperature heat exchanger is communicated with the outside. The expansion machine, the second expansion machine and the third expansion machine are connected with the compressor and the second compressor and transmit power, and the third-kind heat driving compression heat pump is formed.
Description
[0001] Technical field: [0002] The invention belongs to the technical field of power, refrigeration and heat pump. [0003] Background technique: [0004] 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. [0005] The thermal energy (temperature difference) utilization technology represented by absorption heat pump technology can simultaneously utilize the temperature difference between the medium-temperature heat load and the cold ...
