Embodiment Construction
[0070] 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.
[0071] figure 1 The third type of thermally driven compression heat pump shown is implemented as follows:
[0072] (1) Structurally, it is mainly composed of a compressor, a booster pump, an expander, a second expander, a high-temperature condenser, a high-temperature heat exchanger, an evaporator, and a low-temperature condenser; compressor 1 has a circulating working medium channel It communicates with the high-temperature condenser 5, and the high-temperature condenser 5 also communicates with the high-temperature heat exchanger 6 through the booster pump 2. There is also a circulating working medium channel in communication with the evaporator 7, and the evaporator 7 also has a...

The invention provides a third type of heat-driven compression heat pump, which belongs to the technical field of power, refrigeration and heat pumps. The low-temperature condenser has a circulating working medium channel connected to the high-temperature condenser through the compressor, the high-temperature condenser also has a circulating working medium channel connected to the high-temperature heat exchanger through the booster pump, and the high-temperature condenser has a circulating working medium channel connected to the evaporator through the water turbine. The high-temperature heat exchanger also has a circulating working medium channel connected to the evaporator through the expander, the low-temperature condenser has a circulating working medium channel connected to the evaporator through the second booster pump, and the evaporator also has a circulating working medium channel connected to the second expander channel It is connected to the low-temperature condenser, the high-temperature condenser also has a heated medium channel to communicate with the outside, the high-temperature heat exchanger has a high-temperature heat medium channel to communicate with the outside, the evaporator has a low-temperature heat medium channel to communicate with the outside, and the low-temperature condenser has a cooling The medium passage communicates with the outside, and the expander, the second expander, and the water turbine are connected to the compressor and transmit power, forming a third type of heat-driven compression heat pump.
Description
Technical field: [0001] The invention belongs to the technical field of power, heat supply 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] 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 environment and t...
