Energy-saving method for central air-conditioning system

Abstract

The invention discloses an energy-saving method for a central air-conditioning system. The energy-saving method comprises the steps that first operation information is acquired, and the first operation information is a trigger signal generated when an operation body makes contact with or presses an operation panel; a first temperature value is confirmed by taking the first operation information as an analysis basis; first information is confirmed, and if the first temperature value is smaller than the real-time water inlet temperature of a cooling tower, one of valves on a water inlet pipe and a water outlet pipe is closed according to the first information; after operation waits for a preset time, a second temperature value is acquired, and the second temperature value is the temperature value, acquired by a temperature probe on the water inlet pipe, of fluid in the pipe; and the first temperature value is compared with the second temperature value, and if the second temperature value is larger than the first temperature value, the other of the valves on the water inlet pipe and on the water outlet pipe is closed. By means of the energy-saving method, energy consumption of a central air conditioner chilled water system is reduced by nearly 2.0%.

Description

technical field [0001] The invention belongs to the technical field of central air-conditioning, in particular to an energy-saving method for a central air-conditioning system. Background technique [0002] 20-30% of the power consumption of the central air-conditioning system is ineffective consumption, which is wasted. High energy consumption has become a big criticism that restricts the healthy use of central air-conditioning. In addition, there are "big horses and small carts" in the design. The problem of high energy consumption of central air-conditioning is imminent. Current status of unit air conditioner: Screw-type central air conditioner main unit: cooling capacity is 1122KW, cooling power is 240KW, a total of two units. The chilled water circulation pump (referred to as: chilled pump) mainly provides power for chilled water circulation. The input power of a single pump is 37kw, and there are three sets in total, dual-purpose and one standby. [0003] The cooling...
