Indoor unit for base station separate air-conditioning device

Abstract

The invention provides an indoor unit for a base station separate air-conditioning device. The indoor unit comprises a shell; the inside of the shell is provided with a fan blowing air toward the indoor and an indoor heat exchanger; the upper part of the shell is provided with an air inlet, and the air inlet is covered with a filter net; the indoor unit also comprises more than one compressor and a throttle mechanism; the compressor is arranged on one side of the indoor unit, and the indoor heat exchanger and the fan are arranged on the other side of the indoor unit, or the compressor is arranged on the lower part of the indoor unit, and the indoor heat exchanger and the fan are arranged on the upper part of the indoor unit; one end of the throttle mechanism is connected with an outdoor heat exchanger, while the other end is connected with the indoor heat exchanger; the indoor heat exchanger is whole type or separate type, and is inverse L-shaped; and the included angle between the long side edge and the short side edge of the indoor heat exchanger is alpha which is between 30 and 120 degrees. The indoor unit has the characteristics of low production cost, high safety degree, small volume, small overall size, flexible assembly and convenient operation.

Description

technical field [0001] The invention relates to a split air conditioner for a base station, in particular to an indoor unit for a split air conditioner for a base station. Background technique [0002] For telecommunication base stations or other small base stations, it is currently the most commonly used air treatment method to discharge the waste heat generated by equipment by installing an air conditioner in the base station. Since the base station air conditioners generally have a relatively small capacity and the internal space of the base station is limited, the form of the base station air conditioner Mostly split. At present, the common base station split air conditioner has the same settings as the room comfort split air conditioner. The indoor unit includes an indoor heat exchanger and a throttling device; the outdoor unit includes a compressor, a four-way valve, and an outdoor heat exchanger. Because many base stations are located in residential areas, the noise ...

AI Technical Summary

Problems solved by technology

Because many base stations are located in residential areas, the noise of outdoor units is loud, which is likely to cause disturbance to residents; and the installation and maintenance of outdoor units installed on high-rises have certain risks, and are greatly affected by the weather; especially for remote base stations Air conditioners are prone to theft because they are left unattended and inspected for a long time. The compressors of ordinary split base station air conditioners are installed in the outdoor unit, so that once theft occurs, the compressors will often be stolen, resulting in large property losses

[0003] Chinese Patent Document No. CN101109550A discloses a communication base station air-conditioning unit and a method for air circulation in the base station. The integrated air conditioner has a large opening area on the building wall, and many communication base stations are rented. I hate opening holes in the wall. For many buildings, making larger openings in the wall will affect the structural strength of the building; in order to have enough outdoor air to cool the condenser, the integral air conditioner must use a relatively large The power consumption of a large fan is much higher than that of a split machine, but the effect is still not ideal compared with an outdoor heat exchanger

Due to the very narrow space inside the base station, a large number of equipment needs to be configured in the room, and a certain amount of space is required for equipment inspection and maintenance, resulting in relatively strict requirements for the installation size of the base station air conditioner. The air conditioner unit proposed in this patent document has multiple air channels inside. , so that the overall size of the air-conditioning unit is quite large, which is very unfavorable for the transportation and installation of the base station air conditioner, and many problems will be encountered in the layout of the location in the specific base station room
