Embodiment 1

[0044] Such as figure 1As shown, a cooperative device of an atmospheric pressure membrane heat pump and a liquid dehumidification system in this embodiment includes a moisture absorption liquid circulation circuit, a refrigerant circulation circuit and a moisture absorption liquid regeneration circuit. Liquid storage tank 1, solution pump 2, third heat exchanger 9, absorption heat pump branch and dehumidification branch, the liquid inlet end of solution pump 2 is connected with the liquid outlet end of liquid storage tank 1, and the liquid outlet of solution pump 2 The ends are respectively connected to the liquid inlet ends of the absorption heat pump branch and the dehumidification branch; The circulation circuit is connected with the first absorber 4, and the dehumidification branch circuit includes a second electromagnetic valve 10, a cooler 11 and a second absorber 12 connected in sequence by pipelines, and the air inlet 24 of the second absorber 12 is connected to the fi...

Embodiment 2

[0065] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the moisture absorption liquid regeneration circuit in this embodiment also includes a second moisture absorption liquid regeneration circuit, and the second moisture absorption liquid regeneration circuit includes a fifth heat exchange circuit connected in sequence by pipelines. 17, a preheater 18 and a second regenerator 20, the liquid outlet of the second regenerator 20 is connected to the third heat exchanger 9.

[0066] Wherein, the liquid outlet end of the absorption heat pump branch is connected to the liquid inlet end of the first moisture absorption liquid regeneration circuit, and the liquid outlet end of the dehumidification branch circuit is connected to the liquid inlet end of the second moisture absorption liquid regeneration circuit. connect. The liquid outlet end of the first moisture absorption liquid regeneration circuit merges with the liquid outlet end of the...

Embodiment 3

[0073] The difference between this embodiment and Embodiment 1 is that the membrane module described in this embodiment is a plate-fin membrane module; the plate-fin membrane module includes at least two layers of plate membranes 28 arranged in parallel, and two adjacent layers of plate membranes 28 Corrugated plate fins 33 are arranged between them, and the corrugated plate fins 33 form triangular, sinusoidal or rectangular flow passages with the adjacent two-layer plate membranes 28 . The advantage of the plate-fin membrane module is to increase the heat exchange area, disturb the fluid, and enhance the heat and mass transfer.

[0074] Such as Figure 5 As shown, the plate-fin membrane module of the second absorber 12 is formed by stacking multiple layers of parallel plate membranes 28, and each layer of parallel plate membranes 28 is supported by corrugated plate fins 33 and sealing materials 29 to form a triangular flow channel. The corrugated plate fins 33 are triangular...

Abstract

The invention relates to the technical field of absorption heat pump and air humidity control, in particular to an atmospheric pressure membrane heat pump and liquid dehumidification system cooperative device, comprising a moisture absorption liquid circulation circuit, a refrigerant circulation circuit and a moisture absorption liquid regeneration circuit, and the moisture absorption liquid circulation circuit includes A liquid storage tank for containing moisture absorption liquid, a solution pump, a third heat exchanger, an absorption heat pump branch circuit and a dehumidification branch circuit; the absorption heat pump branch circuit includes a first solenoid valve, a first absorber and a first The heat exchanger, the dehumidification branch includes the second electromagnetic valve, cooler and second absorber connected in sequence; the absorption heat pump branch and the dehumidification branch are connected in turn to the moisture absorption liquid regeneration circuit, the third heat exchanger and then return to the storage tank. The device has the functions of heating and air dehumidification at the same time. The heating and dehumidification use the same liquid storage tank and solution pump. The device operates under normal pressure without a compressor, which simplifies the device, reduces costs, and has energy utilization. The advantages of high efficiency and environmental protection.

Description

technical field [0001] The invention relates to the technical field of absorption heat pump and air humidity control, in particular to a cooperative device of an atmospheric pressure membrane heat pump and a liquid dehumidification system. Background technique [0002] In daily life and industrial production, a large number of places need to obtain thermal fluid or raise the ambient temperature, and there are also many places that need to obtain dry air or control the humidity of the gas within a certain range. People often use heat pumps and dehumidifiers with a single function to meet the needs of heating and dehumidification. Only by purchasing two sets of equipment to meet different needs, there are problems of high cost and large footprint, which brings inconvenience to people and easily causes Waste of material and energy. If the two devices are combined into a multifunctional coordination device, it will undoubtedly bring a lot of convenience in life and industry, an...
