Abstract

The invention discloses an efficient condensation gas water heater for mixed heat exchange and a system. The water heater comprises a combustor, a heat exchanger, an equal-pressure smoke cover for separating a spraying system for direct contact heat exchange from the heat exchanger, and a chimney; through reasonable thermal performance design, high-temperature smoke is cooled after heat exchange by the heat exchanger, and no condensed water is generated; due to no need to consider the condensed water corrosion of the heat exchanger, the material grade and the process cost of a dividing wall heat exchange device can be reduced; the spraying system for direct contact heat exchange atomizes and sprays out cyclic spraying liquid to fully absorb latent heat of low-temperature smoke; the cyclicspraying liquid can adopt organic working mediums or water working mediums with safety, no poison, low viscosity and dewatering property; the efficient condensation gas water heater is connected witha heat pump to form an efficiency improvement and energy conservation system, so that the temperature of the cyclic spraying liquid is lowered, the condensation heat transfer efficiency of the low-temperature smoke is further improved, and the overall operation efficiency of the water heater and the system is improved; and the efficient condensation gas water heater effectively improves the overall system operation efficiency, and further reduces the smoke carbon emission through a spraying system.
