Abstract

The invention discloses an air refrigeration and heating central air-conditioning system. The system comprises a large air conditioner compressor, a small air conditioner compressor, a water condenser, an air heat exchanger, an energy storage device, a pressure pump and a circuit control system. An evaporator of a refrigeration system is arranged in an air supply box, and used for cooling air during refrigeration, and during heating, the evaporator is switched to the condenser and used for heating the air. The condenser of the refrigeration system is arranged an air exhaust box, during refrigeration, the condenser absorbs cold energy of indoor and outdoor air, and during heating, the condenser is switched to the evaporator and absorbs heat of the indoor and outdoor air. Therefore, the cold energy and heat in indoor exhaust air can be recycled. By means of the device, air reheating treatment can be conducted, independent control over the temperature and humidity of the air can also be achieved, and the energy-saving effect is remarkable.

Description

technical field [0001] The invention relates to the comprehensive application field of air conditioning and energy saving, in particular to an air cooling and heating central air conditioning system. Background technique [0002] At present, the heat recovery of air-conditioning exhaust air usually adopts the rotary wheel type and the plate-fin type, which has low heat exchange efficiency, and there is penetration and contact between the exhaust air and the fresh air, which pollutes the fresh air and is unhygienic. In addition, this type of air conditioning unit does not have For cold and heat sources, heat exchange equipment should be added, and cold and heat sources should be provided from the outside. [0003] In view of the defect that the waste heat generated by the existing central air conditioner is difficult to recycle in practical application, many units and individuals have proposed some new improvement plans. Although the existing technology effectively uses the...
