Building air-conditioning system with seawater as secondary refrigerant for cooling running water

Abstract

It is about ocean provided cold tap water as the cooling media for architectural air conditioning system. It comprises ocean water filter, water drawing pipeline, water flow sensor, stop valve, multiple-stage centrifugal pump, three way valve, rapid filter, precipitation filter, secondary filter, underground ocean water reservoir, sea water pump, plate heat exchanger, water transmitting pump, underground cold water reservoir, water service pump, air cooling processor, purified water tank, butterfly valve and return pipe. The cold ocean water after treatment through the rapid filter, precipitation filter, and secondary filter exchanges heat with tap water inside the plate heat exchanger, using the original municipal underground pipeline network to transmit tap water, playing both roles of water transmission and cooling. It makes full use of the coldness of the subsurface water, saving a lot of electric power, free from the damage of Freon to the atmospheric ozone layer and it is beneficial to environment protection. It has significant economic and social effects.

Description

technical field [0001] The invention relates to an ocean-cooled building area air-conditioning system, in particular to an ocean-cooled building area air-conditioning system using tap water as a refrigerant, and belongs to the technical field of refrigeration and air-conditioning. Background technique [0002] Most of the existing air-conditioning systems use refrigerant as the working medium and electricity as the energy source, which has complex structure and expensive operation, and cannot be economically used in large-area building areas. A small number of air-conditioning systems that utilize the cooling capacity of the ocean provide limited cooling capacity and are not suitable for long-distance transmission. In the prior art, the invention patent of "Sea Breeze (Air) Air-Conditioning Pipeline System Cooled by Deep Seawater" with the application number 200510036661.0 is to purify and cool the air on the sea surface and then input it into the urban pipe network for util...
