Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to a multi-energy supply device. Background Art

[0002] Heat exchange is the process of heat transfer between two objects or parts of the same object caused by temperature difference. Heat exchange is generally completed through three methods: heat conduction, heat convection and heat radiation. In the current building air conditioning system, the widely used cooling / heating methods are chillers + boilers burning coal, gas or oil and heat pump units, air source heat pumps, ground source heat pumps and water source heat pumps. The advantages and disadvantages of their cooling / heating methods and their scope of application, with the continuous development of heat exchange technology, various types of heat exchange equipment have emerged. In recent years, the heat source tower heat pump system has attracted much attention from users as an energy-saving device that can use high-level energy to make heat flow from low-level heat source air to high-level heat source.

[0003] For example, the authorization announcement number CN 208901496 U, a water vapor suspension condensation heat source tower heat pump heating station, is characterized by a suspended condensation nanofluid absorption heat source system and an ultra-low temperature heat pump valley electricity superimposed heating system. The system has the high heat transfer characteristics of built-in nanofluids and external nano-coated salt spray corrosion resistant alloy fins, absorbs greenhouse fog and haze wet cold heat source renewable energy, and realizes the efficient utilization of wet cold heat source suspension phase change snow frost-free heat absorption. The system compensates for the compressor attenuation in ultra-low temperature environments below -15°C through multi-connected fixed-frequency compressor modules, increases heat and power cogeneration and power output in cold weather, and starts valley electricity superimposed heating devices to compensate for insufficient heat pump heating in cold weather. The system also transports low-temperature cold air to the atmosphere to drive the peak and drive away haze, realizing the economic and social benefits of artificial cold source haze control.

[0004] Using a single heat source tower heat pump system to heat buildings requires a large amount of electricity and does not have cooling capabilities; therefore, the market urgently needs to develop a multi-energy supply device to help people solve existing problems. Utility Model Content
