Special air-conditioning system for textile labs

Abstract

The invention relates to a special air-conditioning system for textile labs, which comprises a refrigerating system, a circulating air duct and a control system, wherein the refrigerating system comprises a finned evaporator which is arranged in an indoor unit as well as a compressor, a finned condenser, an adjustable electromagnetic valve and a gas-liquid separator which are sequentially connected in series in an outdoor unit; one end of the finned evaporator is connected with the finned condenser by a refrigerating pipe; a liquid reservoir, a dry filter, a liquid-feed electromagnetic valve and an expansion valve are sequentially connected in series on the refrigerating pipe; a pipeline connecting the expansion valve with the finned evaporator is in branch connection with a dehumidifying pipeline, and the dehumidifying pipeline is provided with a dehumidifying electromagnetic valve; and the other end of the finned evaporator is connected with the gas-liquid separator by a return-air duct. The special air-conditioning system for textile labs, which is implemented by using the ceiling air supply technology, is used for overcoming the influence of low airflow temperature / humidity control accuracy on textile tests.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to a high-precision special-purpose air-conditioning system for a textile laboratory. Background technique [0002] The textile laboratory is greatly affected by temperature and humidity, and the uniformity of temperature and humidity at each point in the room is extremely high. At the same time, the room has requirements for wind speed. The constant temperature and humidity air conditioners and high-precision constant temperature and humidity machines commonly used in the market are all Can not meet its room accuracy requirements. At present, there are two ways to use air conditioners in textile laboratories: 1. To reduce the control accuracy of the room, it is required to use a precision constant temperature and humidity machine on the market. The humidity control cannot meet the requirements of ±3%, and the air supply from the bottom to the top is used. 2. The room is controlled sep...

At present, there are two ways to use air conditioners in textile laboratories: 1. To reduce the control accuracy of the room, it is required to use a precision constant temperature and humidity machine on the market. The humidity control cannot meet the requirements of ±3%, and the air supply from the bottom to the top is used. 2. The room is controlled separately by an independent dehumidifier, high-precision humidifier, and ordinary air conditioner, which is not energy-saving and the control accuracy cannot meet the temperature and humidity requirements of the room. In addition, it is not a control system, and the unit operates reliably discounted sex
