Device with heating and water-heating device multi-machine parallel system and use method thereof

Abstract

The invention discloses a device with a heating and water-heating device multi-machine parallel system and a use method thereof. The device comprises a heating system, and a water heating circulatory system and a heating circulatory system which are connected with the heating system, wherein the heating system is formed through the parallel connection of a plurality of gas wall-mounted fast heating and water-heating devices; the water heating circulatory system and the heating circulatory system are independent of each other and commonly use the same heating system for heating; and a central controller is used for controlling the heating system, the water heating circulatory system and the heating circulatory system which are connected. The device with the heating and water-heating device multi-machine parallel system, disclosed by the invention, has the characteristics of large load, low noise and low power consumption; and through the design that the water heating circulatory system and the heating circulatory system are independent of each other, the phenomenon that the heat supply is stopped for a long time in the traditional bathing-priority mode is avoided, and the problem of hydraulic imbalance between a heat supply system and the multi-machine parallel system is solved. The invention further discloses the use method of the device.

Description

technical field [0001] The invention relates to the field of heat storage heaters, in particular to a device with a multi-unit parallel system for heating water heaters and a method for using the same. Background technique [0002] The traditional single gas-fired heating water heater has a low thermal load and is suitable for single-family households. It is difficult to apply to places with large load requirements, such as hospitals, schools, hotels and other places. If central heating equipment or large and medium-sized gas-fired heating water heaters are used in these places with large load demands, there will be defects such as loud noise, unsafety, and unreasonable costs, and they will be gradually eliminated by the market. [0003] For this reason, a Chinese patent with a patent number of CN99248707.2 discloses a combined gas heating water heater device, which consists of multiple burners and heat exchangers connected in parallel in a wall-hung boiler to achieve a larg...

AI Technical Summary

Problems solved by technology

The disadvantage of this patent is that the installation flexibility is not strong, and special designs are required for different load requirements, and the burner and heat exchanger affect each other. A combustion heat exchange part is dangerous and other parts will be greatly affected.

However, since the heating pipe and the hot water pipe share the same water storage tank, when bathing, it is easy to cause hydraulic imbalance between the heating pipe and the hot water pipe, which will affect the heating.

For single-family households, the problem of stopping heating in the bathing priority mode caused by hydraulic imbalance may not be a big problem; but for places with multiple households such as hospitals, schools, hotels, etc., it may lead to long-term shutdown Heating, affecting normal life
