Problems solved by technology

When the chiller is running in refrigeration mode, the condenser of the unit must discharge a large amount of condensation heat to the atmosphere (through the cooling water from the cooling tower). Usually, the condensation heat can reach 1.15 to 1.3 times the cooling capacity, and a large amount of condensation heat Directly discharged into the atmosphere, resulting in a la

Abstract

The invention discloses an air-conditioner refrigerating device and heat recovery method, which comprises the following parts: preheating plate heat-exchanger 1, volume heat-accumulating radiators 2, 3, water-hydrothermal pump 4, channel 9, channel pump 10, wherein the volume heat-accumulating supplement radiator 37 is composed by pipe connection within several controlling valves in the relating position. The heat recovery method comprises the following steps: sending the water at 37 deg.c in the refrigerating tower into the preheating plate heat-exchanger 1; preheating the tap water in the tap water radiator at 35 deg.c then injecting the heat-accumulating radiators 2 or 3; sending the water in heat-accumulating radiators 2 or 3 into heat pump condenser6 to heat at 50 deg.c approximately, which generates the domestic heat water and realizes the circulating heating. The heat-accumulating radiator 37 accumulates the heat at night. The device can adjust the operation condition of present central air-conditioner system cooling water group, which saves the energy.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and air conditioning and waste heat recovery, and in particular relates to a condensation heat recovery device and method of a downlink and up-feed hot water circulation system for hotels and hotels. Background technique [0002] Star-rated hotels and hotels require central air-conditioning for cooling in summer, and 24-hour hot water supply. 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 chiller is running in refrigeration mode, the condenser of the unit must discharge a large amount of condensation heat to the atmosphere (through the cooling water from the cooling tower). Usually, the condensation heat can reach 1.15 to 1.3 times the cooling capacity, and a large amount of condensation heat Directly discharged into the atmosphere, resulting in a large ...
