An energy-saving central air conditioner

Abstract

The invention provides an energy-saving central air conditioner. The energy-saving central air conditioner is characterized in that the energy-saving central air conditioner comprises a plurality of cold and heat source systems and a plurality of air conditioning systems; the cold and heat resource systems provide required cold for the air conditioning systems based on the liquid gasification refrigeration principle so as to counteract a cold load in an indoor environment and provide required heat for the air conditioning systems through gas liquefaction so as to counteract a heat load in theindoor environment; the conditioning systems are used for cold-heat exchange regulation of indoor air; the energy-saving central air conditioner further comprises a fresh air system, a central controlunit and a port measurement unit; optimized scientific circuit design is adopted, so that a good energy-saving effect is achieved; and the flow design can ensure high-efficiency utilization of the cold and heat source systems, and energy waste is minimized.

Description

technical field [0001] The patent of the present invention relates to the technical field of central air-conditioning, in particular to an energy-saving central air-conditioning. Background technique [0002] The central air-conditioning system consists of a cold and heat source system and multiple air-conditioning systems. This system is different from the traditional refrigerant air-conditioning system (such as a single unit, VRV) to centrally process air to meet the comfort requirements; the principle of liquid vaporization refrigeration is The air conditioning system provides the required cooling capacity to offset the cooling load of the indoor environment; the heating system provides the required cooling capacity for the air conditioning system hot quantity , to offset the heat load of the indoor environment; [0003] The central air conditioner is mainly composed of a refrigeration system and a water cooling system. The central air conditioner is equipped with indo...

Problems solved by technology

[0004] The above traditional central air conditioners consume a lot of power, have poor power saving performance, and do not have an intelligent optimization processing structure, such as:

[0005] 1. After the central air conditioner is turned on, it provides cooling or heating for each individual office, but the number of office rooms is uncertain, and the central air conditioner needs to be fully activated and work at rated power, which consumes a lot of useless work, wastes electric energy, and is wasted Central air-conditioning mechanical equipment;

[0006] 2. It is impossible to determine the number of people in a room, and the air outlet adjustment provided does not have intelligent automatic control;

[0007] 3. Does not have intelligent residual energy recovery design;

In the case of insufficient load, in order to ensure a better operating state and higher operating efficiency, the refrigeration system can automatically load or unload within a certain range according to the change of the load, but the matching water cooling system still operates at a constant speed for a long time , resulting in a large amount of energy waste and loss of equipment, if no energy-saving measures are taken, energy waste and equipment loss will continue to expand
