Embodiment Construction

[0067] Hereinafter, the hot water supply system 1 according to the present embodiment will be described. here, figure 1 It is a figure which schematically shows the structure of the hot water supply system 1 which concerns on this embodiment. The hot water supply system 1 stores cold and hot water heated by the solar heat collection system 2 in the hot water storage tank 3, and supplies the stored cold and hot water to the hot water supply outlet 6, which is the hot water supply destination. system. The hot water supply system 1 is composed mainly of a solar heat collection system 2 , a hot water storage tank 3 , a hot water supply port 6 , and a controller 8 .

[0068] The solar thermal collection system 2 is a system that collects solar heat and stores the collected solar heat. The solar heat collection system 2 is mainly composed of a solar heat collector 20 , heat medium pipes 21 and 22 , a heat storage tank 23 , and a heat exchanger 25 .

[0069] The solar heat collec...

Abstract

The invention provides a hot water storage tank and a hot water supply system capable of stably performing hot water supply. A hot water storage tank (3) is provided by partitioning the inside of thetank body (30) and storing hot water in the tank body (30) and storing hot water in a high temperature region of hot water stored in the tank body (30). This auxiliary hot water supply device is provided with a sub-heat exchanger (36) provided in a sub-hot water chamber (Rs) for heating hot water stored in a sub-hot water chamber (Rs) and a hot water supply pipe (60) for supplying hot water to a hot water supply destination, and a sub-hot water supply section (45) for introducing hot water stored in the sub-hot water chamber (Rs) into a hot water supply pipe (60).

Description

technical field [0001] The invention relates to a hot water storage tank and a hot water supply system. Background technique [0002] Conventionally, hot water supply systems using renewable energy such as solar energy are known, and their use in dormitories of schools and companies, hotels, and nursing facilities has been proposed, for example. The hot water supply system includes: a solar heat collection system, which collects heat from solar energy; and a hot water storage tank, which stores cold and hot water heated by the collected solar energy, and supplies the cold and hot water to the hot water supply system. destination. In addition, the hot water supply system includes a heating unit that heats the hot water in the hot water storage tank when the temperature of the hot water in the hot water storage tank is low due to insufficient solar energy. As the heating unit, a heat exchanger or the like for exchanging heat between the heating medium heated by the external ...
