Background

The kitchen is the most polluted room in the human living environment. The pollution generated by the processed food in the kitchen is more serious, and the oxygen consumption is increased, carbon dioxide foul gas is generated, carbon monoxide poisonous gas is generated, carbon ash smoke dust is generated, high-temperature oil smoke is generated, and high-temperature steam is generated. With the increase of the sealing degree of the rooms of the human residential buildings, the pollution of the kitchens is serious to an intolerable degree.

The range hood on the market at present has large air exhaust volume, the air in a kitchen can be exhausted after the range hood is opened for 2 minutes, most kitchens are closed, and the kitchen generates serious negative pressure when air is not supplemented; the kitchen is seriously lack of oxygen, a cook is difficult to breathe and supply oxygen, and is not provided with sufficient oxygen for supporting combustion, and the kitchen range can generate serious carbon monoxide toxic gas pollution when the kitchen range is not completely combusted; if the door is opened and the window is opened, the energy of warm air and cold air can be seriously lost.

High-temperature oil smoke and water vapor pollution exist in a kitchen, and an air conditioner is required to cool and dehumidify. To date, there are essentially no refrigerated air conditioning systems in kitchens.

The existing oil fume removing technology has an oil fume (adsorption or cooling) condensate attaching process; the oil condensate is another pollution mode of the oil smoke, and can also hinder the process of the oil condensate besides generating secondary pollution.

The purification and discharge of the oil smoke are the biggest difficult points in the pollution source of the kitchen, and the oil smoke is mixed into grease when meeting cold air after being discharged from a boiler, which is also the main reason for the grease attached inside and outside the range hood. The problem of introducing fresh air into a kitchen is that a common range hood does not seal a channel between a kitchen range and an oil smoke exhaust outlet, and only large air volume is used for exhausting oil smoke.

The air conditioner and the range hood are connected, and the problems of compatibility of the exhaust air quantity of the range hood and the air quantity of each heat exchanger of the air conditioner and load of the air conditioner need to be solved. The large air volume can cause the air in the kitchen to be reduced rapidly, the kitchen can form super strong negative pressure, the stove burning and the breathing and oxygen supply of a cook can be seriously insufficient, and the incomplete combustion can also generate a large amount of carbon monoxide poison gas. The load of the air conditioner can be doubled, and most of the cold energy generated by the air conditioner is exhausted out of the room by the range hood. The air conditioner cannot be used in a kitchen without solving the problem of large air volume discharge of the range hood.
