Central air conditioning centralized control system (intelligent central air conditioning control sy

Central air conditioning centralized control system (intelligent central air conditioning control system), which is a system where an outdoor unit is connected to multiple indoor units, and each indoor unit can run/stop freely. Or groups. Or centralized control. It consists of an outdoor unit and an indoor unit connected by a refrigerant pipe, and the outdoor unit is composed of refrigerant accessories such as an outdoor heat exchanger and compressor. The indoor unit consists of a fan and an indirect evaporator. The outdoor unit can transport refrigerant liquid to multiple indoor units through pipelines, control refrigerant circulation and flow into the indoor heat exchanger, and timely meet the indoor cooling and heating load requirements.

The central air conditioning central controller has the ability to achieve remote intelligent temperature regulation and timing; Excellent temperature regulation technology combined with highly reliable cloud data models can achieve energy conservation and comfort, suitable for indoor temperature control in central air conditioning systems such as offices, teaching, commerce, and stations. By comparing the indoor temperature with the set temperature, the fan coil unit, electric valve, central air conditioning host, etc. at the end of the air conditioning system. It can be controlled to achieve the goals of temperature regulation, comfort, and energy conservation. It can be used in conjunction with the IOT intelligent system of the mobile app, with the ability to set date and time display, preset various wind speed gears, set energy-saving mode, and other intelligent temperature control modes, easily achieving a balance between comfort and energy conservation; Batch centralized management can be achieved through cloud platforms.

Working principle of intelligent central air conditioning system:

The indoor temperature sensor controls the electronic contraction valve on the refrigerant pipeline of the indoor mechanism. After the refrigerant pressure changes, stop variable frequency speed regulation or change the number of outdoor refrigeration compressors, the number of task cylinders, the opening of throttle valves, etc., to change the cooling flow rate of the system and achieve the purpose of refrigeration or heating.

Characteristics of intelligent central air conditioning system:

1. Significant energy-saving effect.

The intelligent central air conditioning system can automatically adjust the compressor speed and change the refrigerant flow rate according to the changes in system load, ensuring the efficient operation of the unit. Reduced energy consumption and annual operating costs during partial load operation.

2. Save building space.

The air-cooled outdoor units used in intelligent central air conditioning systems are generally installed on the roof and do not need to occupy building area. The intelligent central air conditioning system only requires refrigerant pipes and condensate pipes, and the refrigerant pipes are arranged sensitively. Compared to water systems, intelligent central air conditioning systems can reduce building height, reduce building costs, and meet relative indoor ceiling heights.

3. The construction equipment is convenient and reliable in operation.

Compared with centralized air conditioning water systems, the construction task of intelligent central air conditioning systems is much smaller, the construction cycle is short, and they are very suitable for household conditions. The system has fewer links, and the operation and management of the system are safe and reliable.
