Problems solved by technology

However, if you need to change different modes, you need to re-disassemble the position of the fan and motor, which is inconvenient
In addition, the functions of fresh air ventilators currently used in the market are relatively single. When multiple functions are required in precision machine rooms, operating rooms, laboratories and other occasions, multiple units need to be used in combination, which requires a large installation space and high cost.

Abstract

The invention discloses a multifunctional direct expansion type energy recovery and fresh air ventilation all-in-one unit and a control method. The multifunctional direct expansion type energy recovery and fresh air ventilation all-in-one unit comprises a dirty air channel, a fresh air channel, a refrigerant compression loop, an economizer, a dirty air heat exchange loop and a fresh air heat exchange loop. The multifunctional direct expansion type energy recovery and fresh air ventilation all-in-one unit is suitable for places such as precision machine rooms, laboratories, operating rooms, sterile rooms, data centers and the like which require high environmental levels, and has the free combination of multiple functions such as dirty air removal, fresh air conveying, temperature control, humidity control, air filtration, air sterilization, peculiar smell elimination, air purification, deep energy recovery and the like, and different functional requirements are met, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of fresh air ventilators, and in particular relates to a multifunctional direct expansion type energy recovery fresh air ventilator integrated unit and a control method. Background technique [0002] The fresh air ventilator refers to the energy exchange between the exhausted dirty air and the conveyed fresh air through the heat exchanger, and the cooling or heat in the dirty air is transferred to the fresh air as much as possible to achieve the purpose of energy saving. For example, the patent document CN201520687082.1 discloses an energy recovery fresh air ventilator, the motors of the fresh air fan and the exhaust fan are both installed in the fresh air flow channel or both are installed in the exhaust air flow channel. This structure is to improve the layout position of the motor to realize the recovery and discharge of electric heating, so as to adjust the energy utilization rate in different modes. Ho...
