Solar complementary lithium bromide heat pump heating device with mixing distribution function

Abstract

The invention discloses a solar complementary lithium bromide heat pump heating device with a mixing distribution function, belongs to the field of heat supply waste heat recovery and heat distribution, and aims to achieve the effect that heat is reasonably distributed among storage water, the user side and power plant water. The solar complementary lithium bromide heat pump heating device comprises a lithium bromide heat pump, a fourth heat pump, a water mixer, a second water distributor and a water return heat supplementing device, wherein the lithium bromide heat pump comprises a high-temperature heat exchange section, a low-temperature heat exchange section and a middle-temperature heat exchange section, the water mixer comprises a first inlet, a second inlet and an outlet, the water return heat supplementing device comprises a low-temperature heat exchange water pipe, a high-temperature heat exchange water pipe and a first temperature sensor, effect water is subjected to heat exchange through the lithium bromide heat pump and the fourth heat pump, and low-temperature water after heat exchange is returned to a power plant and the first water distributor correspondingly, so thatthe low-temperature water after heat exchange continues to participate in circulation.

Description

technical field [0001] The invention belongs to the field of heating waste heat recovery and heat distribution, and relates to a mixed solar heat supplementary lithium bromide heat pump heating device. Background technique [0002] In recent years, with the increase of urban heating area in my country and the increase of production line construction in industrial plants, the heat consumption in my country has increased rapidly. From the analysis of heating methods, there are currently the following ways for residents to heat in my country: thermoelectricity Combined production mode, central heating of small and medium-sized regional boiler rooms, small domestic gas water heaters, household coal-fired furnaces, etc., among which the combined heat and power mode is a combination of using the high-grade thermal energy of the fuel to generate electricity and then using its low-grade thermal energy for heating Use energy technology. At present, the average power generation efficie...
