Intelligent energy-saving control system of central air conditioner

Abstract

The invention discloses an intelligent energy-saving control system of a central air conditioner, relates to an air-conditioning control system, in particular to an energy-saving control system of the central air conditioner. The energy-saving control system comprises an original water pump control cabinet, a cooling tower, a water segregator, a cooling water pump, a freezing water pump, a water collector, a tail end and a central air-conditioning host, wherein control cabinets are respectively connected with the original water pump control cabinet; a pressure sensor is arranged at an outlet of the cooling water pump; a temperature sensor is arranged at a cooling water inlet / outlet header pipe of the central air-conditioning host; a temperature sensor is arranged at a freezing water inlet / outlet header pipe of the central air-conditioning host; a pressure sensor is arranged at an outlet of the freezing water pump; and each temperature sensor and each pressure sensor are connected with the control cabinets and exchange information with the control cabinets. Through the intelligent energy-saving control system, a water pump system can more adapt to load change; the condition of an integral cooling system after the frequency conversion of the water pumps is considered comprehensively, simultaneously, the intelligent energy-saving control system has the advantages of pressure monitoring, intelligent control process, remote monitoring, simple and convenient operation, obvious energy-saving effect and average electricity-saving rate of 42 percent.

Description

Technical field: [0001] The invention relates to an air-conditioning control system, in particular to an energy-saving control system for a central air-conditioning. Background technique: [0002] With the rapid development of the market economy, energy is far from being able to meet the needs of the market, and the state of the energy gap will not change for quite a period of time. Therefore, the country's energy policy focuses on development and energy conservation. Especially to save precious secondary energy electric energy, the largest user of electric energy in my country is the motor, accounting for about 60%, of which the power consumption of fans and pumps accounts for 35% of the total electric energy. The adjustment of the air volume and water volume of the traditional fan and water pump depends on the adjustment of the damper and the throttle valve. When the demand for air volume and water volume decreases, the opening of the damper and valve decreases; when the ...

Problems solved by technology

Although this adjustment method is simple and easy to implement, it has become a habit, but it is at the cost of increasing the loss of the pipe network and consuming a lot of energy on the damper and valve.

And usually in the design, the design capacity of the user's fan and water pump is much higher than the actual need, which is easy to form the phenomenon of "big horse and small cart" that people often say, resulting in a lot of waste of electric energy
