Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
To the problem that the return air passageway that air conditioner exists is obstructed between as shown the wide row of current half rack of fig. 1-2, the embodiment of the utility model discloses an improve air flow path type and arrange air conditioner between, as shown in fig. 3-4, with the unsettled design of heat exchanger 6, humidifier 2 and converter 3 are placed to the unsettled position in heat exchanger 6 below, and compressor 1 position is with current air conditioner, and heater unit 5 is placed in the lower part of fan system 7. Meanwhile, in the structural design, the electric control cabinet 4, the compressor 1, the humidifier 2, the frequency converter 3, the heater 5 and the fan system 7 are divided into two relatively closed cavities through the heat exchanger 6 and metal plates, wherein the cavities in which the compressor 1 and other components are located are hot air cavities and are air return areas of the air conditioner; the cavity where the fan system 7 and the heater 5 are located is a cold air cavity which is an air supply area of the air conditioner. The heat exchanger 6 and the fan system 7 are designed relatively in the height direction, airflow interference of the compressor 1 is avoided, on the air flow channel path, only resistance exists on the surface of the electric control cabinet 4, and compared with the existing air conditioner, the air flow channel is greatly improved by blocking 50% of the return air area.
