The invention discloses a cold / hot water unit control system and a method for controlling the cold / hot water unit by utilizing the same, aiming to provide a modular cold / hot water unit energy-regulating control system which has a simple structure and has low cost, as well as a control method of the modular cold / hot water unit energy-regulating control system, wherein the control method has high control accuracy, controls stably, and can ensure the working service life of the machine unit effectively. According to the invention, the water inlet temperature and the water outlet temperature which enter each module unit are obtained through the detection by utilizing a water inlet temperature sensor arranged on a general water inlet waterway and a water outlet temperature sensor arranged on a generator water outlet waterway, the operation state of the compressor is regulated according to the water inlet temperature and the water outlet temperature, the machine unit is ensured to be controlled stably in the operation process, and the control is simple; and the control system and the control method provided by the invention can be widely applied in the control field of the cold / hot water unit.
Description
technical field [0001] The invention relates to a modular cold / hot water unit adjustable control system and a method for controlling the cold / hot water unit by using the system. Background technique [0002] Modular cold / hot water unit is a large-scale central air-conditioning unit widely used in factories, office buildings, hotels, etc. It is composed of multiple air-conditioning units with small cooling capacity. Wide range of applications. With the rapid development of my country's economy, the demand for energy has increased greatly, and the power supply has become increasingly tight. Energy-saving air conditioners have been put on the agenda. The traditional control technology is based on the energy regulation of the water inlet temperature of the air conditioning unit, but what users usually require is to ensure the water supply temperature. However, the traditional outlet water temperature adjustment is difficult to respond to the actual load demand, which causes fr...
