Heat supply and cold supply system capable of achieving solar energy and underground water combined energy supply

Abstract

The invention provides a heat supply and cold supply system capable of achieving solar energy and underground water combined energy supply. The heat supply and cold supply system comprises a solar energy heat collecting module, a phase-change heat storing module, a heat supplying and cold supplying terminal module and a temperature and humidity independent control air conditioner module; and different subsystems including a solar energy phase-change heat storing subsystem, a solar energy heat supplying and heating subsystem, a phase-change heating storing, heat supplying and heating subsystem,a solar energy temperature and humidity independent control air conditioner subsystem and a phase-change heat storing temperature and humidity independent control air conditioner subsystem can be formed by the modules through different port switching of four-way valves and three-way valves, and then the functions of heat storing in all year round, heat supplying and heating in winter and temperature and humidity independent control in summer are achieved. According to the system, the total functions are complete, control is flexible, adjusting is convenient, and the building energy saving effect is good.

Description

technical field [0001] The invention belongs to the field of heating, ventilating and air-conditioning, and relates to a composite heating, ventilating and air-conditioning system, in particular to a heating and cooling system for combined energy supply of solar energy and groundwater. Background technique [0002] my country's building energy consumption accounts for about 30% of the total energy consumption, and HVAC energy consumption accounts for more than 60% of the total building energy consumption. Building energy conservation and emission reduction has become an urgent energy problem to be solved. . In 2006, the state promulgated the "Renewable Energy Law of the People's Republic of China", which vigorously advocated the use of renewable energy. In view of the regional differences and instability of renewable energy such as wind energy and water energy, it is difficult to effectively use and promote them in building energy conservation. Solar energy is widely distrib...

[0007] Chinese invention patent application with application number 201610172474.3, a solar heating and cooling system, including: solar collectors, solar circulation pumps, circulating water pumps, cooling water pumps, lithium bromide refrigerators, water storage tanks, cooling towers, hot water pumps and temperature control Although the system solves the technical problem of using solar energy to heat buildings in winter and cool them in summer, it does not consider the problem of energy storage. The system will not operate when there is no solar radiation, nor does it consider the end form of the system. The heat dissipation of traditional heating systems The terminal has high requirements on the temperature of hot water, so it is not suitable for application in solar heating systems
