Embodiment Construction

[0024] The control device and control method of the condenser online cleaning equipment and the central air-conditioning system according to the present invention will be described in detail below with reference to the accompanying drawings.

[0025] The inventors of the present invention noticed that the temperature difference between the outlet water temperature of the condenser and the condensation temperature of the refrigerant can reflect the scaling degree of the condenser. When the scale in the condenser is less and cleaner, the above temperature difference is smaller. When the condenser has a lot of fouling and is not clean, the above-mentioned temperature difference is larger.

[0026] The inventors of the present invention propose that whether to perform the online cleaning operation can be determined based on the monitoring result of the temperature difference between the outlet water temperature of the condenser and the condensing temperature of the refrigerant.

Abstract

The invention discloses a control device and a control method of condenser online cleaning equipment and a central air conditioner. The control device of the condenser online cleaning equipment comprises a temperature sensor and a controller, wherein the temperature sensor is used for detecting the water draining temperature at a water outlet of the condenser, the controller is used for sending an instruction of starting the online cleaning to the condenser online cleaning equipment when the temperature difference between the water draining temperature of the condenser and the condensing temperature of a refrigerant flowing through the condenser is greater than or equal to a first preset temperature difference threshold value. The cleaning device has the advantage that the running of the condenser online cleaning equipment is automatically started by monitoring the actual running parameters, so the amount of dirt of the condenser is controlled within certain range, and higher heat transfer efficiency is guaranteed.

Description

technical field [0001] The invention relates to a central air-conditioning system, in particular to a control device and a control method for condenser online cleaning equipment. Background technique [0002] With the development of my country's urbanization process, more and more large-scale public buildings and residences use central air-conditioning systems for heating and cooling, and the fouling state of the condenser in the central air-conditioning system is very important for the efficient operation of the refrigeration host. [0003] The condenser is the outdoor heat exchanger. The condenser is installed between the compressor discharge port and the throttling device (capillary or electronic expansion valve). The high-temperature and high-pressure gas (refrigerant) discharged from the air-conditioning compressor enters the condenser, and is cooled by copper tubes and aluminum foils, so that the pressure of the refrigerant remains unchanged during the cooling and con...
