Seawater source water ring heat pump device for air-conditioning system

Abstract

The invention provides a water ring heat pump device for exchanging heat by using seawater heat. The device comprises a seawater plate-type heat exchanger, at least one water-water heat pump unit, a heat exchange medium storage device, at least one magnetic valve and a heat exchange medium transportation pipeline, wherein when one magnetic valve is provided, the magnetic valve is positioned on one side of the seawater plate-type heat exchanger; and when two or more magnetic valves are provided, the magnetic valves are positioned on the two sides of the seawater plate-type heat exchanger respectively. The low-grade energy of seawater is subjected to two heat exchange processes through the water ring heat pump device and is transferred to indoor air or hot water, so that the aims of supplying heat, cold, household hot water to the inside of a room are achieved. In the device, heat exchange between a heat exchange medium and the seawater is performed through the seawater plate-type heat exchanger; the water-water heat pump unit is prevented from being corroded when the seawater enters the heat pump unit; and due to the adoption of the mode, the evaporator and the condenser which are made of anticorrosion materials are not required to be used, the initial investment of equipment is reduced and the device is convenient to popularize and apply in reality.

Description

technical field [0001] The invention relates to a heat pump air conditioner, in particular to a seawater source water ring heat pump used in the air conditioner. Background technique [0002] At present, my country's cities mainly rely on coal-fired and oil-fired boilers for heating in winter. In summer, cooling is mainly provided by refrigerators and cooling tower systems. The use of this traditional heating and cooling method not only makes the urban air pollution more and more serious, but also aggravates the energy consumption. The contradiction between supply structure and demand, with the increasing emphasis on urban environmental issues and the adjustment of energy structure, the use of coal-fired boilers for heating has been gradually banned. [0003] Seawater source heat pump is a better way to use seawater as cold and heat source to meet cooling and heating requirements. The temperature of seawater at a certain depth does not change much in winter and summer, much ...
