Energy-saving air conditioning unit having automatic heat recovery controlling function and control method thereof

Abstract

The invention discloses an energy-saving air conditioning unit having an automatic heat recovery controlling function. The energy-saving air conditioning unit solves the problems that existing constant-temperature constant-humidity air conditioning units are high in usage cost and wasteful in energy after being used. The air conditioning unit comprises a refrigerating unit, the refrigerating unit is composed of a compressor, a condenser, a liquid storage pot, a drying and filtering device, an expansion valve and an evaporator which are connected through conveying pipelines sequentially, the evaporator is in back connection with the compressor, and simultaneously, the air conditioning unit is provided with a reheating unit which is in parallel connection with the pipeline between the compressor and the condenser. The air conditioning unit is simple in structure and convenient to use, the power of electrical heating is cancelled due to the application of the technology, the heat which is to be dissipated outdoors is directly led into a room, the requirements of the room for the temperature and the humidity are met, the electrical load is reduced, and energy conservation is achieved, so that the air conditioning unit has high practical values and promoting values.

Description

technical field [0001] The invention relates to an air-conditioning unit, in particular to an energy-saving air-conditioning unit with the function of automatically controlling heat recovery and a control method thereof. Background technique [0002] At present, in order to ensure the control accuracy of the temperature and humidity in the computer room, the constant temperature and humidity air conditioning units produced in China, when the ambient temperature reaches the set value but the humidity does not meet the requirements (humidity is too high), the unit needs to run in dehumidification. Therefore, the compressor It is necessary to continue to work. At this stage, the temperature will drop and it will be greater than the set value. Faced with this state, the existing method is usually to start electric heating to supplement the heat, so that the cooling capacity and heat balance. [0003] However, the traditional electric heating input directly increases the power co...
