Total energy-saving environmental base station air-conditioning

Abstract

The present invention relates to a total energy-saving environmental base station air-conditioning comprises a controlling device and a refrigeration circulating loop formed by connecting with a compressor, a low-pressure reservoir, an indoor steamer, an expansion valve and a condenser in turn. The present invention is characterized in that a new wind cooling device is arranged; the new wind cooling device is composed of a proportion new wind valve and an indoor circulating high-efficiency blower without a volute; and the indoor circulating high-efficiency blown without a volute not only is a steamer blower, but also is a new wind leading-in blower. When outdoor new wind temperature is lower than the set value of indoor temperature, the controlling device is used for controlling and stopping the compressor to run or reducing running efficiency. New wind is leaded in through the indoor circulating high-efficiency blower without a volute. The new wind valve is opened, and new wind opening degree is adjusted to reach the purposes of indoor temperature control and energy saving. At the same time, the compressor uses environmental R407C refrigeration agent and transducer technology. Compared with usual air-conditioning systems, the present invention has the advantages of obvious energy saving, high control precision, energy saving, environmental protection and the like.

Description

technical field [0001] The patent of the present invention relates to an integrated energy-saving and environment-friendly base station air conditioner, specifically an energy-saving and environment-friendly integrated base station air conditioner capable of adjusting indoor temperature through frequency conversion control and fresh air cooling. Background technique [0002] In order to ensure the normal operation of equipment in some special occasions (such as communication base stations, program-controlled computer rooms, etc.), air conditioners are usually required to meet the required temperature and cleanliness in the room. At present, in order to meet the requirement of indoor constant temperature, the conventional air conditioners on the market are usually realized by starting and stopping the compressor, changing the heating capacity of the heater, and changing the speed of the indoor fan in stages. Although conventional air conditioners can meet the requirements of ...

AI Technical Summary

Problems solved by technology

[0003] 1. Poor load adaptability

When the external environment or indoor load changes, it takes a long time for the conventional air conditioner to stabilize the indoor temperature to a new equilibrium point through the start and stop of the compressor and the continuous adjustment of the heater, and consumes a lot of energy.

[0004] 2. There is no fresh air cooling function. The indoor unit of the conventional air conditioner unit is installed in the indoor environment and is isolated from the fresh air outside. Regardless of the temperature of the fresh air, the controller can only detect the indoor temperature and control the cooling or heating of the compressor to adjust the indoor circulating air. , in order to meet the indoor temperature requirements, which makes the natural cooling source unusable and wastes a lot of electric energy

[0005] 3. The control precision is low

[0006] 4. Energy waste is serious

Since the adjustment of the cooling capacity is realized by the start and stop of the compressor and the change of the heating capacity of the heater, the cold and heat offset of the system is relatively large.

[0007] 5. Seasonal energy efficiency ratio is low

Usually, in most of the time, the capacity of the constant temperature air conditioner is greater than the indoor load, which will inevitably cause the phenomenon of "big horses and small carts", the operating efficiency of the system will be reduced, and the cooling and heat will be offset, so the season of the conventional system low energy efficiency

[0008] 6. Compressor life is not high

Due to the frequent start-up of the compressor, its operating life will inevitably be shortened

[0009] 7. Great impact on the power grid

Since the starting current of the compressor is usually 5 to 7 times the rated current, and the frequent starting of the compressor will inevitably cause a greater impact on the outdoor power grid

[0010] 8. Conventional air conditioners only provide one power supply system. When the external power is cut off or the power is cut off, the air conditioner unit cannot work normally, which seriously affects the normal operation of the equipment in the base station and even damages the equipment.
