Water heating system of cold and heat recycling fresh air conditioner

Abstract

The invention relates to a water heating system of a cold and heat recycling fresh air conditioner. The water heating system comprises a fresh air conditioner unit, a living water tank, an air energy hot water unit, a water source cold water unit and a solar water heater, wherein a fresh air inlet is formed in one side of the air energy hot water unit; an air outlet in the other side of the air energy hot water unit is connected with an air inlet of the fresh air conditioner unit through a connection hose assembly; a heat exchange assembly in the air energy hot water unit is connected with the lifting water tank through a circulating pipeline; one side of the water source cold water unit is connected with the heat exchange assembly in the fresh air conditioner unit; the other side of the water source cold water unit is communicated with a water well through a circulating pipeline, and the water discharging side is further connected with the living water tank; the solar water heater is connected with the living water tank through a circulating pipeline. By the adoption of a system structure design capable of realizing three-stage heating, complementary repeated use of water energy, air energy and heat energy can be realized through each set of equipment, and the effects of supplying air by a fresh air conditioner and making hot water are achieved.

Description

technical field [0001] The invention relates to the technical field of fresh air air conditioning systems, in particular to a cold heat recovery fresh air air conditioning hot water system. Background technique [0002] At present, air conditioning and domestic hot water in hotels, hotels, restaurants, bath centers and other places are mostly independent systems. In the south of the Yangtze River, air source hot water units are mostly used to produce domestic hot water, and the air cooled by the evaporator is discharged into the atmosphere during operation; for areas with abundant water resources, water (well water) source chillers are often used to produce chilled water for air conditioning systems During operation, the temperature of the well water rises after the condenser absorbs heat, and most of it is drained or discharged into the backwater well; for areas with tight power supply and sufficient sunshine, solar water heaters are often used to assist in the production o...
