Air-conditioning system improvement method and device for applying all-weather solar heating

Abstract

The invention provides an air-conditioning system improvement method and device for applying all-weather solar heating and relates to the technical field of energy conservation and energy utilization. The air-conditioning system improvement method and device for applying all-weather solar heating are mainly applied to the air-conditioning heating industry. In an original air-conditioning system provided with a single cold host machine used in cooperation with a cooling tower and a boiler, a plate heat exchanger, a solar heat collection plate and an energy storage tank are utilized, and a circulation loop is added. The cooling tower is used for absorbing heat in winter air. The solar heat collection plate is used for absorbing solar photo-thermal energy and then transferring the solar photo-thermal energy to the plate heat exchanger. The single cold host machine is used for absorbing heat of an antifreezing solution. The plate heat exchanger is additionally arranged to form secondary circulation to prevent the antifreezing solution from freezing, and heat can be supplied to indoor users without starting the boiler when the outdoor temperature is above five DEG C; on the condition of not changing the original system and maintaining the summer working performance, the winter heat supply function is increased, the utilization rate of the single cold host machine and the cooling tower is increased, the usage time of the boiler is greatly shortened, the energy utilization rate is increased, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of energy saving and energy utilization, in particular to an air conditioning system transformation method and equipment used in the air conditioning and heating industry. Background technique [0002] At present, the types of cold and heat sources of air-conditioning systems in my country mainly include the following types: 1. Single-cooled air-conditioning host with cooling tower + boiler air-conditioning system; 2. Various types of heat pump air-conditioning systems; 3. Lithium bromide air-conditioning systems; 4. Ice storage + other heat sources air conditioning system etc. Among them, the method of using single-cooling air-conditioning main unit for cooling in summer and cooling tower for heat dissipation, and using boiler for heating in winter has the advantages of flexible application, not limited by project scale, low initial investment, and can be widely used in various buildings. However, the equipm...
