Heat-storage type gas water heating stove for central heating

Abstract

The invention relates to the technical field of gas water heating stoves, and in particular relates to a heat-storage type gas water heating stove for central heating. The gas water heating stove comprises a closed type heat exchange chamber, a closed type air intake chamber, an overheat protection switch, a temperature controller probe head, a water storage tank, a heat exchanger, a burner, a blower, a water pump, an electromagnetic valve, a water flow sensor, a constant temperature water mixing valve and a connecting pipeline. The gas water heating stove has the technical characteristics and construction of heat absorption in a major cycle, and afterheat absorption in an auxiliary cycle; and the operation and stop of a complete machine is controlled according to signals of the temperature controller probe head and the water flow sensor, so as to keep constant water temperature, secondary constant temperature of the water mixing valve and the reasonable connection of the pipelines to ensure equal pressure of cold water and hot water. By using the gas water heating stove disclosed by the invention, thermal efficiency of the product can be remarkably improved, and equal pressure of cold water and hot water can be ensured; and the gas water heating stove has the advantages of rapid heating speed and large water yield, and is not easily affected by environmental climate when in use. The gas water heating stove can be widely used in places which need hot water supply and heating, such as hotels, guesthouses, bath centers, etc.

Description

Technical field [0001] The invention relates to the technical field of gas water heaters, and is a gas water heater suitable for central heating. Background technique [0002] At present, the thermal efficiency of household gas water heaters and wall-hung boilers as hot water equipment has exceeded 100% based on low calorific value, but the heat supply is far from enough for central heating. For boiler series products, the heat supply can meet the requirements of central heating, but there are many shortcomings in actual use. For example, the actual thermal efficiency is difficult to exceed 85% or even lower; some cold and hot water have different pressures, which is inconvenient. Mixed water; the temperature of some hot water is unstable, and the effect is poor when constant temperature water is required. However, solar and heat pump water heaters have extremely high thermal efficiency in a suitable environment, but in winter when hot water is most needed and in high latit...
