Hot water supply controller and manufacture method

Abstract

A hot water supply controller and manufacture method are disclosed for application in an open type hot water storage tank, which uses a control device with arranging a level sensing device, a temperature sensor away from a heating device and a hot water supply temperature sensor for, detecting and controlling the hot water amount , the heating water temperature and hot water supply temperature, and the preset level difference and the temperature difference, and to corporate with a heat pump or heat recovery device of heating systems, water supply, control devices of heating and circulation pump and hot water supply pump, etc, such that according to different needs of the hot water supply and energy-saving control, the hot water supply device is provided with three hot water supply methods: the function of rapid heating and supplying hot water, the function of scheduling hot water supply to meet the hot water demand, and the function of preparing full amount of hot water at off-peak power consumption hours, thereby the hot water supply device is able to enhance and expand the heat release efficiency of the hot water storage tank and the heating operation efficiency of heating cycle of the heat pump system.

Description

[0001] This application is a divisional application for the application number: 201110138475.3 (name of invention: hot water supply device and method and its production and supply hot water control method, application date: May 26, 2011). technical field [0002] The invention relates to a method for controlling the production and supply of hot water, in particular to a method for supplying hot water for heating applications such as open hot water storage tanks and heat pumps or heat recovery. Background technique [0003] Heat pumps or heat recovery devices in the prior art are hot water heating devices of the heat storage type, and generally require large-capacity heat storage tanks, and most of them currently use open heat storage tanks. The hot water supply device should be divided into three operating behaviors, namely, the process of producing hot water by the heat pump or heat recovery heating device, the process of supplying hot water by the open heat storage tank, an...

AI Technical Summary

Problems solved by technology

The heat pump or heat recovery heating device operates or stops according to the hot water temperature setting in the hot water storage tank. The hot water supply process and the makeup water process of the open hot water storage tank operate synchronously, so that the lower temperature cold water of the makeup water directly enters In the hot water storage tank, it is completely mixed with the hot water in the hot water storage tank to reduce the supply temperature of the hot water in the tank, thus reducing the heat release efficiency of the hot water storage tank, resulting in the need to increase more hot water storage to meet the supply The amount of hot water and the temperature demand of hot water supply; In addition, the heat pump often operates at a temperature close to the water supply temperature, resulting in low overall operating efficiency of the heat pump system
