Abstract

Provided are an absorbing/compressing mixed cycle system with a liquid spraying loop and a heat pump heating method. The invention relates to the absorbing/compressing mixed cycle system with the liquid spraying loop. A generator (1), an absorber (9), a second solution flowing path and the liquid spraying loop are included, the generator comprises a generator first heat exchanging channel and a generator second heat exchanging channel; the absorber (9) comprises an absorber first heat exchanging channel and an absorber second heat exchanging channel; a refrigerating agent dilute solution generated in the generator second heat exchanging channel flows through a solution pump (8) and then flows to the absorber second heat exchanging channel; refrigerating agent dry gas and a refrigerating agent saturated solution are generated in a compressor; and the refrigerating agent saturated solution in the refrigerating agent flowing path flows through an ejector and then enters a mixer (4), and is mixed with refrigerant agent wet gas coming from the generator second heat exchanging channel in the mixer (4). Compared with the prior art, the absorbing/compressing mixed cycle system with the liquid spraying loop remarkably lowers the gas absorbing temperature of the compressor, the power consumption of the compressor is lowered, and the system COP is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration / heat pump equipment, in particular to an absorption / compression mixed cycle system with a liquid injection circuit and a heat pump heating method. Background technique [0002] With the rapid development of the global economy and the increasingly severe energy crisis and environmental pollution, it is urgent to develop efficient and clean cooling / heating technologies. As a new way of heat extraction, heat pumps have attracted widespread attention due to their advantages such as high energy efficiency and simple structural features. The more mature refrigeration / heat pump technologies are mechanical vapor compression refrigeration / heat pump technology and absorption refrigeration / heat pump technology. [0003] For the mechanical vapor compression refrigeration / heat pump cycle, currently limited by factors such as refrigerant, cycle, and components, the energy efficiency and operating range o...
