Embodiment Construction

[0031]As shown in the figure, an air-conditioning system transformation method and equipment using all-weather solar heating in the present invention include a cold-only air-conditioning host 1, a cooling tower 2, a boiler 3, a user's indoor air-conditioning system 4, an evaporator 5, and a condenser 6. Add plate heat exchanger 9, add secondary circulation pump 10, add temperature sensor 11, add controller 12, add solar collector plate 13, and add energy storage tank in the original air conditioning system composed of cooling water pump 7 and chilled water pump 8 14. The primary water inlet of the plate heat exchanger 9 is connected to the original cooling water return pipe B1 through the additional pipeline D1, and the connection point between the added pipeline D1 and the cooling water return pipe B1 is located between the cooling water pump 7 and the cooling water pump 7. On the pipeline between the water return valve C; the primary water outlet of the plate heat exchanger 9...

Abstract

The invention relates to an air conditioning system transformation method and equipment using all-weather solar heating, relates to the technical field of energy saving and energy utilization, and is mainly used in the air conditioning and heating industry. It uses plate heat exchangers, solar collector plates, and energy storage tanks in the original air-conditioning system with cooling towers and boilers, and adds circulation lines. Use the cooling tower to absorb the heat in the air in winter, use the solar collector plate to absorb the solar light and heat and transfer it to the plate heat exchanger, use the single cooler to absorb the heat of the antifreeze, and add a plate heat exchanger to form a secondary cycle to avoid antifreeze liquid condensation Ice danger, when the outdoor temperature is above 5 degrees, the boiler can be completely turned off to heat the indoor users. The function of heating in winter has been added without changing the original system and maintaining the working performance in summer, and the efficiency of the single-cooling host and cooling tower has been improved. The utilization rate greatly reduces the use time of the boiler, improves the energy utilization rate and reduces the environmental pollution.

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...
