Problems solved by technology

[0003] At present, various absorption heat pumps have been widely used in various refrigeration, heating, domestic and production hot water supply systems, replacing conventional plate heat exchangers in thermal stations, and effectively increasing the primary side hot water supply of central heating systems. The difference in temperature between supply and return water, but conventional absorption heat pumps are often large in size, which causes difficulties in transportation and installation. Therefore, it is very urgent to reduce the size of the unit or divide the huge unit

Abstract

The invention discloses a split absorbing-type heat exchange unit and a heat exchange method thereof and belongs to the field of heating, ventilating and air conditioning. The split absorbing-type heat exchange unit is composed of a hot-water absorbing-type heat pump, a conventional water-water heat exchanger and a waterway system, the hot-water absorbing-type heat pump is composed of two parts, a generator and a condenser form one part, and an absorber and an evaporator form another part; the waterway system is divided into a primary-side waterway system and a secondary-side waterway system, the primary-side waterway system is sequentially connected with the generator, a high-temperature side of the water-water heat exchanger and the evaporator and then returns to a concentrated heat source, the secondary-side waterway system is divided into two ways, one way is connected with a low-temperature side of the water-water heat exchanger while the other way of the same is connected with the absorber and the condenser, and then the two ways of secondary water join to form one way to supply heat to a user. A split structure is adopted, so that transport size of the unit is reduced effectively, convenience is brought to transporting and mounting, and comprehensive cost is lowered.

Description

technical field [0001] The invention relates to the technical field of heating, ventilating and air conditioning, in particular to a heat exchange unit, in particular to a split type absorption heat exchange unit and a heat exchange method thereof. Background technique [0002] As the scale of urban central heating continues to increase, high-temperature hot water generated by centralized heat sources often needs to be transported over a long distance to reach heat users. In the case of the same heating load, increasing the temperature difference between the hot water supply and return water can reduce the hot water flow, thereby reducing the initial investment of the transmission and distribution pipeline, and reducing the power consumption of the water pump during the system operation, so it can Save heating energy consumption and reduce heating costs. [0003] At present, various absorption heat pumps have been widely used in various refrigeration, heating, domestic and ...
