Description

Double-working medium combined cycle heat pump device
The technical field is as follows:
the invention belongs to the technical field of refrigeration and heat pumps.
Background art:
cold demand, heat demand and power demand, which are common in human life and production; the conversion of mechanical energy into heat energy is an important way to realize refrigeration and efficient heating. In general, the temperature of the cooling medium changes during cooling, and the temperature of the medium to be heated also changes during heating; when the mechanical energy is used for heating, the heated medium has the dual characteristics of temperature change and high temperature at the same time in many times, so that the problems of unreasonable performance index, low heating parameter, high compression ratio, large working pressure and the like exist when refrigeration or heating is realized by adopting a single thermodynamic cycle.
When heat release mainly depends on a condensation process, the loss of temperature difference between a working medium and a heated medium is large, and the loss of a pressure reduction process of condensate is large or the utilization cost is high; the acquisition of low-temperature thermal load is greatly influenced by the pressure reduction of the condensate, and the performance index needs to be improved. The gas compression type heat pump device based on the reverse Brayton cycle requires lower compression ratio, which limits the improvement of heat supply parameters; the low-temperature process is temperature-changing, so that the low-temperature link usually has large temperature difference loss during refrigeration or heating, and the performance index is unreasonable. Meanwhile, the adaptability of the heat pump device based on a single working medium has certain limitation.
The advantages that the low-temperature heat load is absorbed in the evaporation process of the steam compression type heat pump and the high-temperature heat load is provided in the temperature change process of the gas compression type heat pump are kept, the sensible heat of the condensate is fully utilized, and the side effect of the pressure reduction of the condensate is eliminated, namely the heat pump device has reasonable performance index and wide application occasions; the invention provides a double-working-medium combined cycle heat pump device based on the principle of simply, actively and efficiently refrigerating or heating and the principle of coping with different refrigerating demands/heating demands as much as possible.
