Description

Uninterruptible air conditioning system

The invention relates to an uninterruptible electric air-conditioning system.

In order to achieve the effect of energy saving and power saving, the commonly used cooling air generally uses frequency conversion air conditioning. When the frequency conversion air conditioning is started, the compressor will quickly achieve cooling at the highest speed, and adjust the speed according to the temperature change.

However, the conventional technology of 3 tons (30000 BTU/hr) frequency conversion air conditioner in a closed environment and driven by 220 volts of AC power consumes 14-15 degrees of power every 5 hours of operation, so It consumes a lot of electricity. In addition, the conventional technology of 3 tons (that is, 30000 BTU/hr) frequency conversion air conditioner needs continuous power supply from the city power to continue to maintain the operation state. Therefore, if a sudden power failure occurs and the power cannot be continuously provided, As a result, the frequency conversion air conditioner stops running and restarts the air conditioner, which requires a large amount of power. If the air conditioner is always on and off, it will consume a lot of power.

The DC power is at least 48 volts. The detector is electrically connected to the storage unit and the control unit, and the control unit is electrically connected to the converter. The power storage unit is electrically connected to the cooling cycle system; wherein, the control unit sets a power-off reference value and a charge reference value, the detector detects the power generation of the power storage unit and transmits a current power value to the control unit, when the When the control unit determines that the current power value is greater than or equal to the power-off reference value, the control unit controls the converter to stop transmitting the DC power to the power storage unit; when the control unit determines that the current power value is less than or equal to the charging reference value, The control unit controls the converter to allow the DC power to be transferred to the power storage unit for charging, and the power storage unit supplies the DC power of the cold air circulation system.
