Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a heat pump heat recovery type four-stage full-effect fresh air unit. Background Art

[0002] At present, the dual-cold source fresh air unit uses two cold sources with different temperatures to treat the heat and humidity of the fresh air. It has been widely used due to its unique air treatment method. It can be used independently in places where fresh air is needed, such as animal laboratories, medicine, chemical industry and other related fields; it can also be used in combination with other air-conditioning systems in spaces with humidity control needs, such as green smart homes, hospitals, archives, libraries, hotels, airports, railway stations and various work, life and large-scale event venues.

[0003] The dual-cold source fresh air unit in the prior art realizes the cascade utilization of energy through external cold and heat sources and its own cold source to meet the requirements of deep dehumidification. The external cold and heat sources are generally provided by external equipment or refrigeration rooms, and the own cold source often adopts a direct expansion refrigeration system.

[0004] However, the biggest challenge currently faced by dual-cold-source fresh air units with direct expansion refrigeration systems is the problem of how to deal with excess condensation heat. The commonly used approach is to use an external cold source to take away the excess condensation heat, but this approach will increase the cooling capacity of the external cold source and bring additional burden to the external cold source; the excess condensation heat can also be taken away by the condenser in the exhaust duct, but this method is limited in the amount of heat that can be taken away due to indirect heat exchange between the air and the condenser; therefore, it is currently inconvenient to deal with the excess condensation heat.

The spray water in the heat exchange core 23 directly contacts with the air to absorb heat and evaporate, realizing direct evaporative cooling of the air, reducing the air temperature, and the spray water falls into the water collection tray 1 41, and flows back to the water collection tray 2 51 through the water pipe 54; Heating condition: The fresh air treatment process is as follows: the fresh air flows through the filter plate 132 to become clean air, and then is preheated by the heat exchange coil 15. The preheated fresh air is reheated by the heat exchange coil 16, and humidified by the water spray device 25 to reach the fresh air with the supply air temperature and humidity, and is sent into the room through the fan 30; the treatment process from indoor return air to exhaust air is as follows: after the indoor return air exchanges heat with the condensing coil 22 and the condensing coil 21, it is discharged to the outside through the fan 231. In addition, the following explanations are made: First, the heat exchange coil 15 obtains the heat of the refrigeration room through the supply and return water pipe 54 of the refrigeration room, which is used for preheating the outdoor fresh air; second, the heat pump refrigeration cycle process is as follows: the high-temperature and high-pressure refrigerant gas discharged from the compressor 11 flows through the heat exchange coil 2 16 for heat exchange and then cools down, flows through the throttle valve 1 32 for throttling, then flows through the condensing coil 2 22 and the condensing coil 1 21 to absorb heat, and then flows back to the compressor 11; third, the direct expansion refrigeration cycle in the heating condition is closed, and the compressor 2 12 is closed; fourth, the direct evaporative cooling water spray cycle is closed; fifth, the humidification spray cycle process is as follows: the spray water pump 2 52 is turned on in the heating condition, and the water in the water collection tray 2 51 is used to humidify the air through the spray system 2 53.
