Description

technical field [0001] The invention relates to an air source heat pump control system and method, in particular to a smart air source heat pump control system and method based on big data technology. Background technique [0002] An air source heat pump is a device that is driven by a motor and uses a vapor compression refrigeration cycle to transfer the heat in the low-grade heat source air to a high-grade heat source such as water or air. [0003] Existing air source heat pumps have the following deficiencies: [0004] 1. The air source heat pump uses the method of consuming electric energy to exchange heat energy from the air. The existing air source equipment is controlled by a single machine, and most of them are realized by a single chip microcomputer. Because there is not enough storage space, it is impossible to realize a large amount of data storage and historical data analysis. , so fixed operating strategies and parameters are adopted, or the control method of m...

Problems solved by technology

[0005] 2. The existing air source heat pump equipment has the problem of excessive defrosting consumption

The reverse cycle defrosting method mainly has two problems. One is that the defrosting process changes from a heating state to a heat-absorbing state, which is completely negative energy state, resulting in a large loss of heat.

The second is to only use temperature as the condition for judging frosting, which will cause misjudgment of frosting in the absence of frosting and enter the wrong defrosting process, resulting in unnecessary waste of energy

According to the test, the energy consumed by reverse cycle defrosting accounts for about 20% of the total energy consumption of the heat pump, and the problem of energy loss is serious

[0006] 3. For the existing air source heat pump equipment, each set of equipment is installed and operated independently, forming an information "island". For large-scale centralized heating and cooling service providers, it creates obstacles to system information management and cannot realize big data. Acquisition, processing and optimization, it is difficult to provide support for smart city construction
