Abstract

The invention provides a heat-source tower heat pump system based on freeze regeneration and regeneration heat utilization. The heat-source tower heat pump system comprises a refrigerant circuit, a solution circuit, a vacuum maintaining circuit, a vapor circuit, a solution regeneration circuit and a cold and hot water circuit. The solution regeneration circuit comprises a vacuum freeze regenerator, an ice-solution separator, a heat regenerator, a second compressor and other devices. A dilute solution needing to be regenerated in a heat-source tower is sprayed into the vacuum freeze regenerator. Part of water in the dilute solution absorbs heat of the solution to be evaporated under a vacuum environment, the temperature of a residual solution is lowered to the freezing point of the solution, freezing is conducted and ice crystals are separated out, ice crystals are separated out through the ice-solution separator, a concentrated solution is obtained, and the solution is regenerated. Meanwhile, by means of heat released by condensation of vapor, the solution is heated, the reuse of vapor heat is achieved, the solution regeneration problem of the heat-source tower heat pump system is efficiently solved, and the comprehensive efficiency and safe reliability of the heat-source tower heat pump system under various running working conditions are improved.

Description

technical field [0001] The invention belongs to the field of design and manufacture of refrigeration and air-conditioning systems, and relates to a heat source tower heat pump device for regenerating solutions and realizing reuse of steam heat. Background technique [0002] At present, the cold and heat sources of building air-conditioning systems in my country generally adopt three schemes: water-cooled chiller + boiler, air-source heat pump and ground-source heat pump. The heat source tower heat pump system is a new type of cold and heat source solution, which can meet the needs of building cooling in summer and heating in winter at the same time through a set of units. The chiller is idle, and the primary energy utilization rate is low; compared with the air source heat pump solution, its operating efficiency is higher in summer (equal to water-cooled chiller), and the finned tube evaporator can be completely avoided during the heating operation of the air source heat p...
