Solar stand-alone machine hot water system

Abstract

The invention discloses a novel solar stand-alone machine hot water system. The hot water system comprises a heat collection unit, a heat supply unit and a control unit; the heat collection unit comprises a solar stand-alone machine, a water tank and a first heating device, a water inlet of the water tank is connected with the solar stand-alone machine, and the first heating device is installed in the water tank; the water tank comprises a hot water tank and a cold water tank which are arranged side by side; the heat supply unit comprises a water terminal, a thermostatic valve, a second heating device and a system pipeline; the thermostatic valve is provided with a hot water inlet end, a cold water inlet end and a mixed water outlet end; the system pipeline comprises a hot water supply pipe, and a thermostatic device, a circulating device and a second heating device are sequentially mounted on the hot water supply pipe; the system pipeline further comprises a cold water inlet pipe, a water return pipe and a branch water pipe; the control unit comprises a controller, and the controller is electrically connected with the thermostatic valve, the circulating device, the heating device and the electromagnetic valve. The invention provides the hot water system capable of realizing zero cold water, capacity increase of hot water and constant-temperature water outlet.

Description

technical field [0001] The invention relates to the field of solar water heating systems, in particular to a solar single-unit water heating system. Background technique [0002] The existing solar stand-alone units are basically installed on high-rise buildings, far away from the indoor water end, and the downpipe is long. There are many water points in the house, and each water point is farther away from the solar water tank, so it takes a lot of time before use. A large amount of cold water also consumes the limited hot water in the pipeline, resulting in a waste of hot water resources and greatly increasing the cost of use; when multiple water points use hot water at the same time, hot water supply is prone to occur Insufficient phenomenon, unable to meet the needs of multiple users to use hot water at the same time; in addition, when users use hot water, they need to adjust the water mixing valve according to the remaining heat of the water tank, causing a lot of inconv...
