Low-noise type ultrathin overhead type frequency-conversion shelter air conditioner

Abstract

The invention relates to a low-noise type ultrathin overhead type frequency-conversion shelter air conditioner which mainly comprises chassises, an outdoor heat exchanger and an indoor heat exchanger, wherein the outdoor heat exchanger comprises two axial flow fans, a condenser and a frequency-conversion compressor, the condenser is installed on a chassis in an outdoor casing, and the vibration center line of the frequency-conversion compressor is superposed with the center line of the width direction of the chassis; and the indoor heat exchanger comprises an evaporator, an expansion valve, a filter, a volute-free centrifugal blower and an evaporator cover, wherein the evaporator is installed in the center of a chassis of the indoor heat exchanger, a chassis of an inner ring of the evaporator is provided with a return air inlet with an air deflector, four air outlets are evenly arranged on a chassis of an outer ring of the evaporator, the evaporator, the return air inlet, the air deflector and the four air outlets are all packaged in the evaporator cover, and the volute-free centrifugal blower is fixed below the evaporator cover and is correspondingly consistent to the center of the return air inlet. The invention has reasonable design, compact structure, balanced running of the air conditioner, low noise, large air output and good refrigeration effect and is suitable for a shelter air conditioner with high requirement to an indoor working environment to use.

Description

technical field [0001] The invention relates to a shelter air conditioner, in particular to a low-noise ultra-thin roof-mounted frequency conversion air conditioner for the shelter. Background technique [0002] To provide a good working environment for electronic equipment and operators under harsh weather conditions, it is necessary to adjust the temperature in the shelter. Due to the diversity and particularity of the equipment structure of the shelter, the most effective space for the shelter is the top of the shelter. Therefore, the researchers developed the roof-mounted air conditioner to meet the working needs of the shelter. [0003] For example, the patent No. 200620170700.6 discloses an ultra-thin top-mounted inverter air conditioner, which mainly includes a condenser installed on the outdoor heat exchange side, a condensing axial flow fan, an evaporator installed on the indoor heat exchange side, an evaporating centrifugal fan, and a horizontal air conditioner.

Problems solved by technology

[0004] In order to solve the unreasonable installation position of the air conditioner compressor in the shelter in the prior art, the compressor is close to the return air outlet of the air conditioner, the vibration is unbalanced, the operation noise is loud, the cooling effect of the compressor is poor, the working environment in the shelter is poor, and the cooling performance of the air conditioner is low, etc. Insufficient, the present invention provides a cabin air conditioner compressor with reasonable installation position, balanced vibration, low operating noise, no heat conduction between the compressor and the cabin, good heat dissipation effect of the compressor, and low-noise ultra-thin air conditioner with good refrigeration performance Top-mounted inverter shelter air conditioner
