Heat storage and cold storage circulation system

Abstract

The invention provides a heat storage and cold storage circulation system which comprises a heat exchange module. The heat exchange module and a hot water incubator communicate to form a first circulation system body specially used for supplying hot water. The heat exchange module and an energy storage incubator communicate to form a second circulation system body for storing heat and cold. The first circulation system body and the second circulation system body are provided with a control valve for selectively switching the two system bodies and controlling switching on or off of the two system bodies. The energy storage incubator further communicates with the heat exchange module and indoor heat exchange terminal equipment to form a third circulation system body for regulating room temperature, and the third circulation system body is controlled by a valve independently. A first coil pipe connected with a tap water inlet pipe is arranged in the energy storage incubator. A second coilpipe communicating with an original water heater or other hot water usage terminals is arranged in the hot water incubator, and the first coil pipe communicates with the second coil pipe. The heat storage and cold storage circulation system is reasonable in structure, efficient and multifunctional, solar heat energy in spring, autumn and winter can be stored in a heat preservation mode and used for increasing the room temperature, night cold capacity of regions with a large day and night temperature difference in hot seasons can be stored and used for decreasing the room temperature, and thepracticability is high.

Description

technical field [0001] The invention relates to a solar water heating system, in particular to a heat storage and cold storage cycle system. Background technique [0002] The existing solar water heating system uses solar heat collectors to collect solar heat, fully converts the sun's light energy into heat energy under the irradiation of sunlight, and automatically controls the circulation pump or solenoid valve and other functional components to collect the heat from the system through the control system. The heat is transmitted to the large-scale water storage and heat preservation water tank, and the water in the heat preservation water tank is heated by assisting corresponding power, gas, fuel oil and other energy sources. [0003] Existing solar water heating system is to be installed on the roof or high place by bearing water pressure type thermal insulation water tank and bearing water pressure type solar thermal conduction plate. Because of the pressure, the requir...

Problems solved by technology

The same reason restricts the house of ordinary families to install only six square meters or three conventional solar thermal panels, and a small water heater with a thermal insulation tank volume of less than 300 liters, so that the heating utilization efficiency of the solar water heating system is very low and cannot be replaced. More effectively share and replace the functions and costs of traditional energy such as electricity, gas, and fuel oil. With the improvement of social progress and people's living standards and requirements, the utilization rate and multi-functional use range of solar energy need to be further developed.
