Abstract

The invention provides a cooling system of a variable-frequency air conditioner as well as a cooling control method and a cooling control system of the variable-frequency air conditioner. The cooling system is applied to variable-frequency equipment of the variable-frequency air conditioner and comprises a branch pipeline and an electromagnetic valve, wherein the two ends of the branch pipeline are respectively communicated with an inlet of an enterprise separator and the inlet of a compressor of the variable-frequency air conditioner; at least a part of the branch pipeline is in contact with a cooling unit of the variable-frequency equipment; the electromagnetic valve is used for connecting or disconnecting the branch pipeline; the branch pipeline is connected when the temperature of the cooling unit is higher than a preset temperature upper limit. The branch pipeline is connected with an air and liquid separator of the variable-frequency air conditioner in parallel, and the two ends of the air and liquid separator have a small pressure difference, so a part of a low-temperature coolant can flow through the branch pipeline, and the low-temperature coolant can take away the heat of the cooling unit in order to cool the variable-frequency equipment. The cooling system disclosed by the invention can be used for solving the problem of the electric energy waste existing in an existing cooling system.

Description

technical field [0001] The present application relates to the technical field of air conditioning, and more specifically, to a heat dissipation system of an inverter air conditioner and a heat dissipation control method and system thereof. Background technique [0002] The drive controller is the core control component of the inverter air conditioner, which plays an important role in the operation of the inverter air conditioner. In order to achieve the purpose of frequency conversion, the drive controller is equipped with a frequency conversion device for driving the inverter compressor. Due to its large output power , and its heat dissipation is also large. In order to ensure the normal operation of the frequency conversion equipment, it must be cooled and dissipated. At present, the cooling fan is generally used to force the cooling. Since the cooling fan needs to consume a certain amount of electric energy, there is a problem of wasting electric energy.
