Abstract

This invention belongs to the field of refrigerating air conditioner and waste heat recycling technology. In details, it is a kind of combined central air conditioner refrigerating and heat recycling system and method. It is composed of preheating board type heat exchanger, heat storage tank, water-water heating pump machine and controlling valve, all of which connected though pipes and connected with pipes of original living water tank, heat supply board type heat exchanger and cold water machine condenser. The system can take out 37íµ water flowed from cold water machine condenser, partially send to preheating board type heat exchanger to heat tap water. The preheated water send to heat storage tank in one way and boiler house as replenishing water in another way. The water from heat storage tank is sent to heating pump condenser of water-water heating pump machine to further cycle heating to 50íµ and used as domestic heat water.

Description

technical field [0001] The invention belongs to the technical field of refrigeration air conditioning and waste heat recovery. In particular, it relates to a central air-conditioning waste heat recovery system and method. Background technique [0002] Star-rated hotels and hotels require combined central air-conditioning for cooling and 24-hour hot water supply in summer. In most cases, the cold and heat sources are set separately, and the cooling capacity is provided by the chiller, and the hot water is provided by the steam or hot water boiler. When the water chiller is running under cooling conditions, the condenser of the unit has to discharge a large amount of condensation heat to the atmosphere (through the cooling water from the cooling tower). Usually, the heat of condensation can reach 1.15 to 1.3 times of the cooling capacity, and a large amount of heat of condensation is directly discharged into the atmosphere, resulting in a large waste of energy, and severe hea...
