Abstract

The invention provides an integrated negative pressure square bin air conditioning system and a control method. The integrated negative pressure square bin air conditioning system is characterized in that a fresh air inlet is formed in the side face or the top of a square bin laboratory; a first nylon filter, a first evaporator, a G4 primary filter, a bag type medium efficiency filter, a second evaporator, a first condenser, an electric heater and an air feeder are sequentially arranged on a fresh air channel from the fresh air inlet to the inside, and the air feeder is arranged on an air feeding window; the square bin laboratory is connected with an air return window, and the air return window is inwards sequentially provided with a plurality of layers of disinfecting and filtering parts and an exhaust centrifugal machine; and a second condenser is arranged on the side edge, one side of the second condenser is connected with the environment through a condensation fresh air inlet, and the other side of the second condenser is provided with an axial flow fan. According to the integrated design, indoor air treatment, air conditioner condensation waste heat recycling and an exhaust system are integrated into one unit. The material consumption of an air pipe system is reduced, the free heat recovery design is adopted, the investment of electric heating is reduced, and the purpose of saving energy is achieved.

Description

technical field [0001] The invention relates to the technical field of air source heat pumps, and more specifically relates to a negative-pressure square warehouse laboratory air-conditioning system and a control method. Background technique [0002] The traditional shelter air conditioner includes three sets of independent subsystems: the air out part unit subsystem, the split unit outdoor unit subsystem and the independent exhaust subsystem. The three subsystems are installed independently, occupying the installation space of the vehicle shelter, and There are many air ducts in the air conditioning unit; the refrigerant pipes take up space. In particular, the vehicle-mounted cabin air conditioner is required to be used under fresh air conditions, and it must be used under all operating conditions where the fresh air temperature ranges from -15°C to 40°C, and the supply air temperature is guaranteed to be between 18°C ​​and 26°C. Traditional shelter air conditioners genera...
