Full pre-mix condensing heating hot-water dual-purpose device

Abstract

The present invention relates to a whole premixing condensing space heating and water heating double duty device, which comprises a burning generating part, a cyclical delivering part, a heat exchanging part and a control part. The burning generating part comprises a whole premixing burner and a fuel gas and air ratio controller, the heat exchanging part realizes the heat exchanging of fume and water, and comprises a condensing heat exchanger and a plate type heat exchanger, the cyclical delivering part comprises a fume exhaust pipe, an air inlet pipe, a condensate water discharging pipe and a water circulating pump and a blower fan, realizes air and fuel gas delivering for the burning generating part, and the hot fume discharging, deliveries hot fume and water to the heat exchanging part, and discharges low-temperature fume and high-temperature water; the control part is arranged in the whole premixing condensing space heating and water heating double duty device, and comprises a processor controlling each part work flow, and sensors are arranged at the cyclical delivering part, the heat exchanging part and the burning generating part, thus the purposes of thermal efficiency improving and foul gas discharging reduction are realized.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a heat exchange device with dual functions of a heater and a water heater realized by using a fully premixed condensing type. Background technique [0002] At present, gas water heaters on the market only use the sensible heat in the flue gas produced after gas combustion, and its temperature exceeds 110 degrees Celsius to 130 degrees Celsius, otherwise the condensed water will fall on the surface of the burner in the water heater, affecting the combustion effect and damaging burner. Because in the heat loss of the water heater, except for the loss of the outer wall of the water heater, which is shared by everyone, which accounts for about 2%, most of the heat loss belongs to the exhaust heat loss, and the higher the temperature of the flue gas, the greater the exhaust heat loss and the lower the thermal efficiency. . Since the exhaust gas temperature of an ordinary gas water heater is...

Problems solved by technology

However, its pointer is for water heaters, and it is not proposed to be applied to other related fields. More importantly, the heat exchanger needs to adopt spiral coil or horizontal S-shaped fins, and at the same time, it is subject to material problems corroded by condensed water, resulting in high manufacturing costs. , it is very difficult to promote the market
