Heat pump type cold and heat source unit capable of achieving frost-free and evaporative cooling

Abstract

A heat pump type cold and heat source unit capable of achieving frost-free evaporative cooling comprises a refrigerant circulation loop, a spraying water or water solution circulation loop and a water solution regeneration system circulation loop, wherein the refrigerant circulation loop comprises a compressor, a four-way reversing valve, a user-side heat exchanger, a throttle valve, an environment-side heat exchanger and a communication pipe I, a water or water solution pool, a circulating pump and a sprayer are arranged in the spraying water or water solution circulation loop, an inlet of the circulating pump is communicated with the water or water solution pool through a connecting pipe, an outlet of the circulating pump is communicated with the sprayer through a connecting pipe, water or a water solution is sprayed in the environment-side heat exchanger of the refrigerant circulation loop or a cooling tower communicated with the environment-side heat exchanger through the sprayer, and a solution heater, a high-pressure pump, a reverse osmosis device and a reverse osmosis pressure regulating valve are arranged in the water solution regeneration system circulation loop. The heat pump type cold and heat source unit is high in refrigerating / heating capacity and efficiency and has very important significance on energy saving and environmental protection.

Description

technical field [0001] The invention relates to a cold and heat source unit, in particular to a heat pump type cold and heat source unit capable of realizing frost-free and evaporative cooling. Background technique [0002] Heat pump type cold and heat source units include air-cooled heat pump type cold and heat source units and water-cooled heat pump type cold and heat source units, both of which can be used for heating and cooling. "Air-cooled" and "water-cooled" are customary terms that do not always mean cooling, but sometimes also mean heat source. For example, when heating, the heat pump absorbs heat from the "wind" or "water". The outdoor heat exchanger of the air-cooled heat pump type cold heat source unit is a heat exchanger that directly exchanges heat between the refrigerant and the outdoor air. For heating, the outdoor heat exchanger acts as an evaporator through which the heat pump circulates to absorb heat from the outside air. At this time, the outdoor air ...
