Description

Technical Field

[0001] This utility model relates to the field of heat recovery technology for air conditioning outdoor units, specifically a fresh air central air conditioning unit with heat recovery function. Background Technology

[0002] A central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. The system uses the principle of liquid vaporization refrigeration to provide the required cooling capacity to the air conditioning system in order to offset the heat load of the indoor environment. When the fresh air conditioner cools the indoor environment, it will discharge heat into the air through the outdoor unit of the air conditioner.

[0003] Chinese patent disclosure CN213713300U discloses a heat recovery device for an air conditioner outdoor unit. It includes a base, a storage mechanism, and a heating mechanism. The storage mechanism is located on the top front side of the base and is connected to the air conditioner outdoor unit. The heating mechanism is located on the upper left side of the storage mechanism. This invention utilizes the heat energy emitted by the air conditioner outdoor unit, allowing it to enter the storage mechanism and fully utilize the heat energy. This heat then heats the water source, providing hot water when needed, thus saving energy.

[0004] However, it still has the following drawbacks: the device uses heat-receiving pipes to absorb heat emitted by the outdoor unit of the air conditioner, but the heat recovery method is singular, only utilizing the heat-receiving pipes to absorb heat from the air, resulting in very low heat conversion efficiency. Therefore, we propose a fresh air central air conditioning unit with heat recovery function to solve this problem. Utility Model Content
