Four-tuyere fresh air heat pump dehumidifier device

Abstract

The invention relates to the field of air conditioners, and discloses a four-tuyere fresh air heat pump dehumidifier device. The four-tuyere fresh air heat pump dehumidifier device comprises a shell, a first draught fan, a second draught fan and a multifunctional dehumidification and reheating device, wherein the first draught fan, the second draught fan and the multifunctional dehumidification and reheating device are arranged inside the shell, the shell is provided with an indoor air return opening, an indoor air supply opening, an outdoor air exhaust opening and an outdoor air supply opening, and a ventilation pipeline is communication with each other which is arranged between the indoor air return opening, the indoor air supply opening, the outdoor air exhaust opening and the outdoor air supply opening, the multifunctional dehumidification and reheating device is internally provided with a function module used for dehumidifying and heating an air of an indoor and a function module for carry out balancing the internal condensation liquid after the function is switched, the first draught fan feeds the air of the indoor into the ventilation pipeline through the indoor air return opening, and the second draught fan conveys the air treated by the multifunctional dehumidification and reheating device in the ventilation pipeline into the indoor. The four-tuyere design of the flat rectangle is small in occupied space and easy to install, the reheating component is beneficial to carry out heating the dehumidified cold air, the energy can be saved while the comfort requirement is met when the dehumidified cold air enters the indoor, and the balance utilization of the internal refrigerant can be kept.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a four-outlet fresh air heat pump dehumidifier device. Background technique [0002] Existing fresh air air-conditioning units use 5 or 6 outlets, which makes it difficult to arrange air ducts on site, takes up a lot of space, wastes a lot of materials, increases equipment, and seriously affects the height of buildings. Some do not have a heat recovery module, and the exhaust gas is discharged directly, which wastes energy; some are equipped with a heat recovery module for heat exchange through the exhaust gas, which has low efficiency and insufficient heat energy for the air, and cannot heat the air entering the room to a comfortable temperature in colder weather ; Some heat utilization modules are equipped with heat pump energy for preheating, but the mode of heating the air cannot be changed, and it is easy to overheat. The refrigerant in the module cannot be pumped back into ...

[0002] Existing fresh air air conditioners use 5 or 6 outlets, which makes it difficult to arrange air ducts on site, takes up a lot of space, wastes a lot of materials, increases equipment, and seriously affects the height of the building

Some do not have a heat recovery module, and the exhaust gas is discharged directly, which wastes energy; some are equipped with a heat recovery module for heat exchange through the exhaust gas, which has low efficiency and insufficient heat energy for the air, and cannot heat the air entering the room to a comfortable temperature in colder weather ; Some heat utilization modules are equipped with heat pump energy for preheating, but the mode of heating the air cannot be changed, and it is easy to overheat. The refrigerant in the module cannot be pumped back into the system to participate in the work, resulting in the uncertainty of the amount of refrigerant used in the reheating module, too much waste, and too little will cause the dehumidification function of the dehumidification module to be insufficient
