Embodiment Construction

[0065] 2 Working principle of heat pump system

[0066] The air source heat pump system mainly includes evaporator, compressor, condenser and expansion valve, in addition to terminal equipment such as water pump, solenoid valve and heat preservation water tank. Its working principle is: the low-temperature and low-pressure refrigerant vapor from the evaporator, after being pressurized by the compressor, becomes a high-temperature and high-pressure refrigerant gas, and then discharged into the condenser, and then passes through the condenser and the heat transfer medium (water) The high-temperature and high-pressure gas is liquefied into a high-pressure liquid refrigerant, and then becomes a low-temperature and low-pressure gas under the pressure reduction of the throttling device (capillary or expansion valve) and flows to the evaporator, and the refrigerant evaporates and absorbs heat under the evaporator After boiling, it turns into refrigerant vapor and is sucked by the suc...

Abstract

The invention discloses a BP network predicting based air source heat pump hot water system design method. An air source heat pump temperature predicting control design method is included and comprises a unit water outlet temperature predicting control scheme, water outlet temperature BP network predicting module setup and a water flow rolling optimization algorithm. According to the method, the temperature control self-adaptive capacity is high, and the requirement of heat pump temperature online control can be met.

Description

technical field [0001] The invention relates to a design method of an air source heat pump hot water system. Background technique [0002] In 2015, the National Development and Reform Commission mainly promoted the implementation of the "coal-to-electricity" plan, that is, to replace gas heating with heat pump heating. In this project, the air source occupies a leading position among many heat pump technologies due to its low energy consumption and small footprint. Air source heat pump heating systems have been installed in most cold regions. However, due to the non-linearity, time-varying, large time-delay and strong coupling of the air source heat pump heating system, some manufacturers use water flow regulation technology, combined with logic control and PID regulation to ensure the constant temperature of the water outlet of the unit, but the constant temperature effect is not good. At present, scholars at home and abroad are researching related intelligent control meth...
