Operating control method and device, air conditioning water machine system and storage medium

Abstract

The invention provides an operation control method and device, an air conditioning water machine system and a storage medium. The air conditioning water machine system is provided with a host water pump and a plurality of parallel water machine units. The operation control method comprises the steps of determining the indoor capacity demand value according to the set water temperature of the specified location, the actual water temperature of the specified location and the operation flow rate of the host water pump; determining the total capacity output value of any one jointly-operating watermachine unit according to the ambient temperature and actual water temperature of any one water machine unit; calculating the capacity demand difference value between the total capacity output valueof any set of one jointly-operating water machine unit and the indoor capacity demand value; and determining which jointly-operating water machine unit is to be started for operation according to thecapacity demand difference value. With the technical scheme of the present invention, the system operation reliability is further increased, more energy is saved, while comfort is also improved, the frequent start-stop phenomenon of the water machine units is reduced, and prolonging of the compressor life and retarding of the impact damage to the circuit are facilitated.

Description

Technical field [0001] The present invention relates to the technical field of air conditioners, and in particular to an operation control method, an operation control device, an air conditioner water machine system and a computer-readable storage medium. Background technique [0002] In related technologies, the start-up of parallel water-turbine units is generally considered to set the number of water-turbine units or the ratio of the number of units to start, such as 50%. After the air-conditioning water-turbine system is running, the capacity is adjusted according to the water temperature of the single water-turbine unit. The output value is easy to cause system misjudgment. Too many water turbine units are likely to be operated, exceeding the indoor capacity demand value, and wasting energy. If it is a fixed speed unit, it is easy to cause a single unit to start and stop frequently, causing water temperature fluctuations. ; If it is a frequency conversion unit, the output of...

[0002] In the related technology, the start-up of parallel water-generating units is generally considered to set the number of water-generating units or the ratio of the number of starting units, such as 50%. After the air-conditioning water-generating system is running, the capacity is adjusted according to the water temperature of a single water-generating unit The output value is likely to cause misjudgment of the system, and it is easy to cause too many water turbines to be operated, exceeding the capacity demand value of the indoor side, wasting energy. If it is a fixed-speed unit, it is easy to cause a single unit to start and stop frequently, resulting in water temperature fluctuations ; If it is a frequency conversion unit, the capacity output of a single unit will be less than 50%, and the frequent start and stop all year round will have a relatively large impact on the life of the compressor and the impact on the circuit in the electric control box
