Embodiment 1

[0026] The first type of absorption heat pump is also called heat-increasing heat pump. Such as figure 1 As shown, a test device of the first type of absorption heat pump unit includes an evaporator side circulation pipeline 3 connected to the evaporator and a condenser side circulation pipeline 2 connected to the condenser, and the evaporator side circulation pipeline The pipeline 3 communicates with the condenser side circulation pipeline 2 through the water mixing circulation pipeline, and the water mixing circulation pipeline is provided with a water mixing pump controlled by frequency conversion and a valve for controlling the opening and closing of the pipeline. The connected generator side circulation pipeline 4, the generator side circulation pipeline 4 is connected with a heat exchanger 5, and the heat exchanger 5 is connected to a heat source, through which the heat exchanger 5 will enter the circulation of the generator 1 The water is warmed up, that is, the low-te...

Embodiment 2

[0029] Such as figure 2 As shown, on the basis of Example 1, an auxiliary heat exchanger 10 is connected to the generator side circulation pipeline 4, and the auxiliary heat exchanger 10 is located between the heat exchanger 5 and the outlet of the generator 1 , the auxiliary heat exchanger 10 is also connected to the condenser side circulation pipeline 2, and is arranged between the cooling water pump 6.2 and the inlet of the condenser. Through such an arrangement, the low-temperature circulating water flowing out of the generator 1 passes through the auxiliary heat exchanger 10 and exchanges heat with the medium-temperature cooling water in the condenser-side circulation pipeline 2, and then enters the heat exchanger 5 to be heated by an upstream external heat source. , which undoubtedly reduces the input of the heat source, and the temperature of the cooling water is lowered after heat exchange, thereby reducing the input amount of the cold source that plays a role in bala...

Abstract

The invention belongs to the heat pump set testing technical field, and specifically relates to a first type absorption heat pump set testing device comprising an evaporator side circulation pipelineconnected with an evaporator and a condenser side circulation pipeline connected with a condenser; the evaporator side circulation pipeline and the condenser side circulation pipeline are connected through an add water circulation pipeline; the device also comprises a generator side circulation pipeline connected with a generator; a heat exchanger is arranged in the generator side circulation pipeline, connected with a heat source, and used for heating up the circulating water entering the generator; the generator side circulation pipeline is in a closed circulation mode. The testing device can fully utilize the heat energy formed in testing, can prevent heat energy waste, and can reduce the resource input and operation cost of the testing device, thus saving energy.

Description

technical field [0001] The invention belongs to the technical field of heat pump unit testing, and in particular relates to a first-type absorption heat pump unit testing device. Background technique [0002] Absorption heat pump is a circulation system that uses low-grade heat sources to pump heat from low-temperature heat sources to high-temperature heat sources. It is an effective device for recycling low-temperature heat energy and has dual functions of saving energy and protecting the environment. The absorption heat pump can provide both cooling and heating, realizing a dual-purpose machine. In recent years, as the absorption heat pump has been widely valued and used in the industry and air-conditioning industry, the test equipment for the absorption heat pump unit has also been improved. requirements. Existing testing devices for absorption heat pump units have defects such as large energy consumption, high operating costs, and long debugging time, which easily lead ...
