Problems solved by technology
However, the air source heat pump air conditioner using the above-mentioned surface-cooled air heat exchanger has the problems of low cooling efficiency and high energy consumption due to the poor heat dissipation effect of the surface-cooled air heat exchanger during cooling operation in summer; Sometimes, because the surface of the surface-cooled air heat exchanger is prone to frost, frequent defrosting is required, so there is a problem that the defrosting operation needs to consume a lot of heat energy and cause heat energy waste
In addition, the connection distance between the surface-cooled air heat exchanger of the current air source heat pump air conditioner and the refrigeration compressor cannot be too far, otherwise the exhaust resistance of the compressor will increase and the work efficiency will decrease. Therefore, the air source heat pump of the prior art All air conditioners adopt a structure in which a surface-cooled heat exchanger, a refrigeration compressor and refrigeration accessories are assembled in a shell, and are installed outdoors as a whole. Although the refrigerant pipes and accessories are insulated, energy dissipation is inevitable. , will also reduce the efficiency of the air conditioner
In addition, the structure of the surface cooling heat exchanger determines that it cannot be made into a large-capacity heat exchanger, which makes it difficult to manufacture a large-scale unit for the current air-source heat pump air conditioner. The existing technology uses multiple air-source heat pumps connected in parallel to form a huge The air-conditioning unit group is used in large buildings, and this kind of parallel air-conditioning system has the problem that the system is difficult to match reasonably, resulting in a low energy efficiency ratio of the entire air-conditioning system
In addition, the relative cost of the current surface cooling heat exchanger air source heat pump air conditioner is relatively high, so it is difficult to promote and use it as an air conditioning system for large buildings

Description
technical field [0001] The invention relates to a novel air source heat pump air conditioner. Background technique [0002] The current air source heat pump air conditioner uses a fan and a serpentine finned coil surface cooling heat exchanger to exchange heat with the air. The heat exchanger acts as an evaporator in winter to absorb heat from the outside air, and acts as a condenser to discharge indoor heat to the air in summer. In the outdoor air, it can realize air-conditioning operation. It has the characteristics of simple structure, convenient installation, and no external heating equipment is required for heating. However, the air source heat pump air conditioner using the above-mentioned surface-cooled air heat exchanger has the problems of low cooling efficiency and high energy consumption due to the poor heat dissipation effect of the surface-cooled air heat exchanger during cooling operation in summer; Sometimes, because the surface of the surface-cooled air heat...
