Air conditioning system for spinning workshop and control method

Abstract

The invention discloses an air conditioning system for a spinning workshop. The system comprises an exhaust adjusting window, a fresh air adjusting window, a return air adjusting window, a condensation pump, a cooling adjusting valve, a heating adjusting valve, a shower nozzle and a water circulation system and further comprises a frequency converter, a temperature and humidity and flow detection piece, a central controller unit and a monitoring unit. The invention further discloses a regulating method for the air conditioning system. The method comprises the steps of: the central controller unit calculates indoor and outdoor enthalpy values of the spinning workshop by applying an enthalpy value calculating formula and compares results; when the outdoor enthalpy value is greater than the indoor enthalpy value, the exhaust adjusting window and the fresh air adjusting window are closed, and the return air adjusting window is thoroughly opened, and the central controller unit controls freeze water and / or steam heating to adjust air; and when the outdoor enthalpy value is smaller than the indoor enthalpy value, the central controller unit firstly controls the exhaust adjusting window, the fresh air adjusting window and the return air adjusting window in real time according to a set value, and then regulates by combining the freeze water and / or steam heating. By utilizing a natural energy source, consumption of steam and freeze water is reduced, and consumption of electrical energy is reduced.

Description

technical field

[0001] The invention relates to the technical field of air conditioning in spinning workshops, in particular to an air conditioning system and control method for spinning workshops. Background technique

[0002] In the textile workshop of the textile industry, in order to meet the requirements of the production process, the temperature and relative humidity of the workshop need to be controlled within the allowable range. Textile air conditioning plays an important role in the textile production process. At present, there are many forms of air conditioners used by textile enterprises in our country, and manual control is still used, but the general requirements and functions are the same. The dust content is controlled within the allowable limit, and at the same time, enough fresh air should be kept in the workshop to benefit the health of the operators. Textile mills are enterprises with high energy consumption, and the electricity consumption of textile a...
