Description

Single-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 mechanical energy is used for heating, the heated medium has the dual characteristics of temperature changing and high temperature at the same time, so that the problems of unreasonable performance index, low heating parameter, high compression ratio, too large working pressure and the like exist when refrigeration or heating is realized by adopting a single thermodynamic cycle theory.

Specifically, when heat release mainly depends on a condensation process, the loss of temperature difference between a working medium and a heated medium is large in a vapor compression heat pump device based on reverse Rankine cycle; meanwhile, the condensate is large in loss or high in utilization cost in the pressure reduction process; when the supercritical working condition is adopted, the compression ratio is higher, so that the manufacturing cost of the compressor is high, the safety is reduced, and the like; in both cases, the adverse effect on obtaining low temperature thermal load is difficult to eliminate. Similarly, a gas compression heat pump apparatus based on a reverse brayton cycle requires a low compression ratio, which limits the improvement of heating parameters; meanwhile, 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 not ideal.

Undeniably, the vapor compression heat pump has the advantages of absorbing low-temperature heat load in the evaporation process, and the gas compression heat pump has the advantages of variable-temperature heat release; if the advantages of the two can be kept, the sensible heat of the condensate is fully utilized, and the side effect of the pressure reduction of the condensate is eliminated, the obtained heat pump device has reasonable performance index, so that the application occasions of the heat pump device are enlarged. Based on comprehensive consideration, the invention aims to simplify, actively and efficiently use mechanical energy for refrigeration or heating from the principle of simply, actively and efficiently using mechanical energy, and provides a single-working-medium combined cycle heat pump device.
