Solar energy and gas combined thermostatic water heater and regulating method for thermostatic hot water outflow

Abstract

The invention relates to a solar energy and gas combined thermostatic water heater and a regulating method for thermostatic hot water outflow. The thermostatic water heater comprises a solar water storage device and a gas water heater; a cold water inlet pipe of the solar water storage device communicates with tap water; the gas water heater includes a gas valve, a water inlet valve, a water inletpipe, a gas proportional valve, a hot water outlet pipe, a burner and a heat exchanger; the thermostatic water heater is characterized in that the gas water heater further includes a controller, a water inlet temperature probe, a first water flow sensor, a cold water inlet pipe, a second water flow sensor, a hot water outlet temperature sensing probe and a water proportional valve assembly; and the controller is electrically connected with the water inlet temperature probe, the gas valve, the first water flow sensor, the gas proportional valve, the second water flow sensor, the hot water outlet temperature sensing probe and the water proportional valve assembly. The thermostatic water heater has the advantages that all-weather stable hot water supply can be realized; a user does not needto frequently regulate mixed water; solar energy can be utilized to the maximum degree; the consumption of gas is greatly reduced; water outlet temperature is stable; and the thermostatic water heateris comfortable to use, economical, energy-saving and environmental-friendly, and is capable of effectively avoiding the situation that people are scalded due to the fact that the water temperature ofa solar water heater is overhigh.

Description

technical field [0001] The invention relates to a constant temperature water heater combined with solar energy and gas and a method for adjusting constant temperature hot water output. Background technique [0002] The realization of the function of solar water heater basically depends on the weather, so the stability of its hot water supply is often not guaranteed. Therefore, how to make use of the solar water heater to make the outlet temperature reach the required requirement becomes a problem to be solved. Since ordinary solar water heaters are in use, the temperature may be different every day and at each time period, and the temperature may attenuate during use, requiring the user to adjust the mixed water at any time, which is extremely inconvenient to use. In addition, there is generally a certain amount of cold water in the outdoor pipes, and it is impossible to realize instant hot water, and the solar water temperature may reach 95°C, which may cause burns if you ...
