Embodiment Construction

[0035] In order to facilitate those of ordinary skill in the art to better understand the essence of the present invention, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, the multi-energy composite hot water system control method with predictive calculation function includes the following steps:

[0037] 1. Calculate the average water temperature of the user in the last 7 days (if less than 7 days, take the current number of days) and average water consumption Calculate the average heat consumption Q, the calculation formula is as follows:

[0038] Q = cρ T ‾ V ‾

[0039] Among them, c represents the specific heat capacity of water, and ρ represents the density of water.

[0040] 2. The system automatically reads the temperature infor...

Abstract

The invention provides a multi-energy composite hot water system control method with a pre-judgment calculation function. The control method comprises the steps of 1) calculating the average heat consumption quantity Q within a period of time by use of the system, 2) correcting the average heat consumption quantity Q according to the weather forecast air temperature information and configuring the supply water quantity V and the heat storage temperature T of a heat accumulation water tank according to the corrected average heat consumption quantity, 3) calculating the heating capacity Q solar energy of a solar heat source system, and 4) calculating the running time of a heat pump by use of the system, calculating the desired heating time t of the heat pump according to the surplus heat quantity Q surplus, and setting a water temperature detection time interval t1, the start time t1-t of the heat pump and the like. The multi-energy composite hot water system control method with the pre-judgment calculation function is used for effectively avoiding the heating of excessive water each day, reducing waste, improving the operating efficiency of the heat sources, fully developing the advantages of the various heat sources, and saving more energy.

Description

technical field [0001] The invention relates to the control field of water heating devices, in particular to a multi-energy compound hot water system control method with predictive calculation function. Background technique [0002] Solar water heater is an economical, energy-saving and environmentally friendly water heater, widely used in production and domestic hot water supply. However, one of the biggest problems in the use of solar water heaters is that the heating capacity is not enough in rainy days. In order to solve this problem, the methods currently adopted are auxiliary heating with electric heating wire, auxiliary heating with air source heat pump water heater and auxiliary heating with gas. [0003] However, these current multi-energy composite hot water systems are generally equipped with a hot water storage tank to store the prepared hot water, and the volume of the hot water storage tank is generally designed according to the per capita water consumption an...
