[0013] When the temperature difference of waste heat is large, the structural form of single-stage generator-condenser and double-stage absorption-evaporator can be used in series (such as figure 1 ), fully transfer the waste heat to the hot water of the secondary network to achieve a better effect of reducing the temperature of waste heat. Such as figure 1 As shown, a unitary hot water heat pump includes 1 generation-condenser module 1, 2 absorption-evaporator modules 2, 3, solution heat exchanger 4, primary network hot water inlet pipe A and generation-condensation The generator of the generator module is connected, and the generator of the generator-condenser module is connected with the hot water outlet pipe B of the primary network; The condenser of the condenser module 1 is connected, and the condenser of the generator-condenser module is connected to the hot water outlet pipe D of the secondary network; the hot water inlet pipe of the second secondary network is connec...

[0015] When the temperature difference of the primary network hot water (driving hot water) is large, the structural form of a two-stage generation-condenser and a single-stage absorption-evaporator in series can be used (such as figure 2 ), the two-stage generator can realize the cascade use of heat energy, and greatly reduce the temperature of the primary network water. Such as figure 2 As shown, a unitary hot water heat pump includes 2 generation-condenser modules a, b, 1 absorption-evaporator module d, solution heat exchanger 4, primary network hot water inlet pipe A and the first Connect the generators of the generator-condenser module a, connect the generators of the two generator-condenser modules a and b in series, and finally connect the generator of the second generator-condenser module b to the hot water outlet pipe of the primary network; Network hot water inlet pipe C is divided into two routes, the first secondary network hot water inlet pipe is connected to t...

[0017] When the temperature difference between the inlet and outlet of the hot water in the primary network and the residual hot water is large, the structural form of a two-stage generation-condenser and a two-stage absorption-evaporator can be connected in series (such as image 3 ), so that the waste water is reduced to a lower temperature. Such as image 3 As shown, a unit type hot water heat pump includes 2 generation-condenser modules 1, 2, 2 absorption-evaporator modules 7, 8, solution heat exchanger 4, primary network hot water inlet pipe A and the second Connect the generator of 1 generator-condenser module 1, connect the generators of 2 generator-condenser modules in series, and finally connect the generator of the second generator-condenser module 2 to the hot water outlet pipe B of the primary network; Network hot water inlet pipe C is divided into two routes, the first secondary network hot water inlet pipe is connected to the condenser of the second generator-co...

Abstract

The invention provides a unit type hot water type heat pump which comprises m generation-condenser modules, n absorption-evaporator modules and a solution heat exchanger. The unit type hot water type heat pump is characterized in that the standard unit modules are designed, and through different combinations, the heat pump adapts to requirements of different conditions. The modules are respectively and independently designed, manufactured and formed with generation-condensing and evaporation-absorption as unit levels, and the matched assembling modes of the unit levels can be selected according to different conditions so that the heat pump can achieve the optimum waste heat recycling effect. Through the unit module type, the design workloads are reduced, the production material supply period is shortened, the different station requirements can be met, and possibility is provided for mass production and application of the heat pump.

Description

technical field [0001] The invention belongs to the field of heat pumps, in particular to a unit type hot water heat pump. Background technique [0002] When hot water heat pumps are used in urban thermal secondary heating stations, they often exist in an integrated form. During use, it is specially designed according to the working conditions of different thermal stations. For different outlet water temperatures, there are various ways of generator-condenser and evaporator-absorber stages, which is not conducive to commercial production and serial design. At the same time, the integrated design is bulky and cannot be moved or placed in some places. Contents of the invention [0003] In order to solve the above problems in the prior art, the present invention proposes a unitary hot water heat pump, which is characterized by the design of standardized unit modules, which can meet the requirements of different working conditions through different combinations. The module ...
