Problems solved by technology

[0002]At present, the air conditioning system used to control the ambient temperature is mainly composed of indoor heat exchanger and outdoor heat exchanger. It can realize the temperature regulation of the condensing agent, thereby indirectly changing the indoor ambient temperature. This kind of air conditioning system does not save energy very well.
In some seasons of the year, such as winter and spring and autumn, when the outdoor temperature is lower than the set temperature of the indoor heat release area and indoor and outdoor air convection cannot be performed, there is no system that can The indoor temperature can be controlled without turning on the high-energy-consuming compressor. Even in this case, the existing air-conditioning system has to start the high-energy-consuming compressor, especially those with high heat generation and high cleanliness requirements. In the workplace, the temperature is controlled by the environment. This kind of solution that still uses the heat pump system to cool down is not energy-saving, resulting in unnecessary waste of electric energy and high operating costs.

Abstract

The invention discloses a heating-cooling type heat pipe and heat pump combined circulating system which mainly comprises an evaporator, a condenser, a heat pump, a throttling valve, a liquid storage tank, a gas-liquid two-phase flow pipe, a circulating pump, a four-way valve, an electromagnetic valve, a check valve, mutually connected pipelines and a temperature adjusting and control portion. A heat exchange type power heat pipe system and a heating-cooling type heat pump circulating system are combined to realize a heat energy transferring system. The whole device comprises a heat pipe heat exchange system, a heat pump refrigerating system and a heat pump heating system. When cooling is needed even if the indoor set temperature is lower than the outdoor temperature, heat pump cycle is used for refrigerating; when heating is needed even if the indoor set temperature is higher than the outdoor temperature, heat pump cycle is used for heating; and when the indoor set temperature is higher than the outdoor temperature and cooling is needed, the heat pipe device starts to operate, and heat exchange is completed by the aid of heat pipes. The heating-cooling type heat pipe and heat pump combined circulating system integrates the heat pump and heat pipe techniques and improves refrigerating efficiency.

Description

technical field [0001] The invention belongs to the technical field of heat energy transportation, and relates to a cold and warm heat pipe heat pump composite cycle system for cold and heat energy transportation formed by combining a heat pipe heat exchange system and a heat pump refrigeration and heating system. Background technique [0002] At present, the air-conditioning system used to regulate the ambient temperature is mainly composed of indoor heat exchanger and outdoor heat exchanger. This air-conditioning system can realize the temperature regulation of the condensing agent through the high energy consumption of the compressor in the indoor heat exchanger, thereby indirectly changing the indoor temperature. Ambient temperature, this air-conditioning system does not save energy very well. In certain seasons throughout the year, such as winter and spring and autumn, when the outdoor temperature is lower than the set temperature of the indoor heat release area and ind...
