Kitchen air conditioning system
Technical Field
The present invention relates to a kitchen air conditioning system.
Background
The kitchen is a main place for people to cook, the mood of a cooking person is directly influenced by the good or bad of the kitchen air environment, particularly in hot summer, the kitchen sultry environment brings great discomfort to the cooking person, and for this purpose, various kitchen air conditioners are invented by people to cool the kitchen air.
The existing kitchen air conditioner has no great difference from the common air conditioner in basic form, and is generally split by adopting an inner machine and an outer machine, namely the outer machine is positioned outdoors, the inner machine is positioned indoors, the inner machine and the outer machine are respectively provided with a motor fan, the split type kitchen air conditioner of the inner machine and the outer machine is connected in a pipeline mode, holes are formed in a wall to damage decoration, the outer machine is hung outside, the structure is not compact enough, and the whole kitchen air conditioner is not attractive. In addition, the existing kitchen air conditioner is provided with an outdoor air inlet and an indoor air outlet, outdoor fresh air enters the air conditioner through the outdoor air inlet and is supplemented into the kitchen from the indoor air outlet after heat exchange of the heat exchanger, namely, the air conditioner works in a fresh air mode, and for extreme weather in summer or cold, the energy consumption of the air conditioner is high due to the fact that the temperature of the outdoor air and the temperature of the indoor air are high, energy conservation is not facilitated, and heat generated by heat exchange of the air conditioner cannot be effectively utilized. It can be seen that the existing kitchen air conditioner is not organically combined with the range hood, and heat generated by the air conditioner heat exchanger cannot be discharged through the range hood.
In addition, as people pay more and more attention to energy conservation and environmental protection, people pay more and more attention to not only the pollution problem of the oil smoke discharge to the environment, but also the problem of heat waste caused by the oil smoke discharge, however, in the working process of the traditional range hood, the heat carried by the oil smoke discharged outside is not effectively utilized before being discharged into a public flue or outdoors, so that heat waste is caused.
