Abstract

The invention discloses a control method of a hot water supply system, and belongs to the technical field of supply systems. The control method specifically comprises the steps as follows: (1) turning on a power source; (2) reading system data; (3) judging a system setting mode and turning on an electromagnetic valve to be in a standby state; (4) waiting for flowing of water; (5) judging water quantity; (6) calculating the number of water heaters needing to be started; (7) judging whether the number of already-started water heaters is smaller than or equal to the number of the water heaters needing to be started; and (8) shutting off the water heaters according to a firstly starting and firstly shutting manner. The control method has the beneficial effects that a corresponding number of water heaters can be automatically controlled to be started to output water according to the hot water demand quantity for practical use, so as to accord with the hot water demand quantity for practical use. Therefore, a traditional boiler can be replaced through parallel connection and the control of multiple water heaters, and higher safety and simplicity are achieved.

Description

A kind of control method of hot water supply system

Technical field

The invention discloses a kind of control method of hot water supply system, belong to the supply system technical field.

Background technology

For the supply of hot water, have and utilize boiler, also have and utilize water heater, with regard to the person that utilizes the boiler, its hot water supply is bigger, thereby can be applicable to that the hot water demand measures big environment, for example restaurant or the like; As for water heater, its hot water supply is less, although has the water heater of large size to be developed, and still can't let single water heater be applicable to that the hot water demand measures big environment, therefore, still utilizes boiler to be applied to the hot water demand at present and measures big environment.Can supply a large amount of hot water though use boiler; But it is except using oil acts as a fuel; Also oil storage tank must be arranged, will operate boiler combustion even also must be licensed practicing engineer, therefore causes it to have significant drawback dangerous and trouble concurrently.

Summary of the invention

The control method that the purpose of this invention is to provide a kind of hot water supply system can be according to actual hot water demand's amount of using, and the water heater of automatically controlling respective numbers starts water outlet, in order to solve the deficiency in the above-mentioned technology.

The objective of the invention is to realize through following technical scheme: a kind of control method of hot water supply system, its concrete steps are:

(1) power-on;

(2) reading system data;

(3) judge default form and opens solenoid valve standby;

(4) wait for water flows;

(5) judge the water yield;

(6) the water heater quantity of the required startup of calculating;

(7) judge whether the water heater quantity that has started is less than or equal to the water heater quantity of required startup;

(8) close the orderly close-down water heater earlier according to opening earlier.

The invention has the beneficial effects as follows: can be according to actual hot water demand's amount of using; The water heater of automatically controlling respective numbers starts water outlet, to meet hot water demand's amount of actual use, and therefore can be with the parallel connection and the control of many water heaters; And the replacement conventional boiler has higher security and simplification.
