Variable-frequency central air conditioner control system

Abstract

The invention discloses a frequency conversion central air-conditioning control system, comprising: a gas processor, which includes a heat exchanger and a fan placed on one side of the heat exchanger, and the heat exchanger is provided with a water inlet and a water outlet; The compressor motor that provides chilled water for the heater is provided with a chilled water inlet and a chilled water outlet. A chilled water inlet pipe is connected between the chilled water inlet and the heat exchanger outlet, and the chilled water outlet is connected to the heat exchanger inlet. A chilled water outlet pipe is connected between the water ports; a chilled water temperature sensor installed on the chilled water inlet pipe and chilled water outlet pipe; a chilled water pump installed on the chilled water outlet pipe; a cooling device connected to the compressor motor; at least one for a temperature and humidity sensor for measuring the temperature and humidity of the air; and a controller electrically connected to the gas processor, the compressor motor, the chilled water temperature sensor, the chilled water pump, the cooling device and the temperature and humidity sensor respectively. The system can adjust the cooling output in real time according to the change of air heat and humidity load, thus saving energy.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to a frequency conversion central air conditioning control system with energy saving effect. Background technique [0002] In industrial production, many kinds of equipment have certain requirements on the temperature and humidity of the working environment. If the humidity and humidity are too high, their normal operation or performance may be affected. For example, in the automobile manufacturing industry, most of the molds used to produce auto parts are metal molds. When the air humidity in the production workshop is high, the surface of these molds will absorb water vapor and gradually rust, which will affect the normal use of the molds. For this reason, people install frequency conversion central air-conditioning control system in the production workshop to adjust the temperature and humidity of the air, avoid the rust of metal molds caused by excessive air humidity, and provide a ...

Problems solved by technology

However, when the temperature and humidity of the air is reduced to a certain level, the heat load and humidity load generated by the conditioned air will be reduced, but at this time, the central air conditioner still adjusts the temperature and humidity of the air according to the initial air conditioning range, while The cooling capacity output cannot be adjusted in real time according to the reduced heat load and humidity load, thus wasting cooling capacity in vain
