Embodiment Construction

[0049] Now in conjunction with accompanying drawing, the present invention will be further described:

[0050]As shown in the figure, 1. a solar heat pump composite hot water system control method, is characterized in that, comprises the steps:

[0051] (1) Determine whether the controller has completed the initialization of the system parameters. The initialization includes the heat collection cycle, the temperature difference between the start and stop of the water tank cycle, the running time of the return water cycle, the start and stop temperature, and the initialization of the fault flag. When the initialization is completed,

[0052] (2) Test the bottom area of ​​the water tank; the controller automatically opens the water supply valve, detects and records the liquid level of the water tank before water intake, the water flow rate, the time of water intake, and the liquid level of the water tank after water intake, and then calculates and determines the bottom area of ​​...

Abstract

The invention discloses a control method of a solar heat pump composite hot water system. The method comprises following steps: firstly, whether a controller completes initialization of system parameters or not is judged; secondly, after initialization is completed, the bottom area of a water tank is tested; thirdly, heating power of a heat pump at the different water tank hot water temperatures is tested; fourthly, whether a user completes setting of simple parameters or not is judged, if yes, the parameters are updated, and if not, default use parameters are determined according to a conventional use scene; fifthly, whether the user needs to use water in a timing manner or not is judged, if yes, in order to ensure water using requirement of the user, timing constant-temperature water supply is adopted, and if not, water is supplied according to the conventional total amount; sixthly, according to hot water enthalpy, energy of hot water finally needed by the user is analyzed and determined; and seventhly, the moment value is recorded at intervals of fixed time, and the water tank temperature value and the water tank liquid level value at the moment are measured. The method has the beneficial effects of being high in automation degree and saving energy.

Description

technical field [0001] The invention relates to a control method for a solar heat pump composite hot water system. Background technique [0002] Due to the simple form and easy realization of solar thermal utilization, the scale of solar energy engineering applications is getting larger and faster. [0003] At present, the control systems of most solar water heaters are mainly aimed at household solar water heaters. Although there are already many controller products on the market, most of them have more or less problems. The main performance is that the control method used is relatively simple and the control logic is relatively complicated, resulting in low control accuracy and intelligent control. The level is not high, the interface display is monotonous, the switch cannot be automatically controlled, the control can not achieve the ideal effect, and the energy saving goal cannot be truly achieved. Moreover, the demand for engineering applications has put forward high...
