An energy-saving variable working condition full-range accurate adjustable air-conditioning system and its control method

Abstract

The invention discloses an energy-saving variable working condition air-conditioning system with the precisely adjustable whole range and a control method thereof. The operation process of the air-conditioning system comprises the following steps that low-temperature and low-pressure refrigerant gas from an evaporator is absorbed by a compressor and is compressed into high-temperature and high-pressure gas through the compressor, then the gas enters a water cooling condenser and an air cooling condenser respectively to give off heat to air / water so as to be condensed into high-temperature and high-pressure liquid, the liquid is throttled through a throttling device to be a gas-liquid two-phase body which is then evaporated into low-temperature and low-pressure gas through the fact that the evaporator absorbs air heat, the low-temperature and low-pressure gas is then absorbed by the compressor, and the circulating is conducted repeatedly. The energy-saving variable working condition air-conditioning system with the precisely adjustable whole range is reasonable in design, efficient, saving in energy, suitable of variable working conditions, capable of achieving water saving operation, high in environmental adaptability, high in adjusting precision, high in intelligent degree, high in safety performance, and stable and reliable in operation, saves energy, meets the energy saving and environmental protection policy advocated in China, can achieve the purposes that the air outlet working condition is free of blind areas and is precisely adjustable, and provides a stable and reliable operation environment for various application occasions.

Description

technical field [0001] The invention relates to the technical field of air-conditioning control, in particular to an energy-saving and variable working condition full-range precise adjustable air-conditioning system and a control method thereof. Background technique [0002] Existing air-conditioning products that can realize precise adjustment of temperature and humidity generally include the following two types: constant temperature and humidity air conditioners and temperature-adjustable dehumidifiers. [0003] Constant temperature and humidity air conditioners use one or more compressors with fixed capacity to control the temperature or humidity of the room by starting and stopping the compressors. Since the compressors cannot control the temperature and humidity at the same time, only one of the indicators can be prioritized for control, resulting in temperature and humidity accuracy. The adjustment is not high. In addition, the dew-point air that has been cooled and d...
