Description

Split-type modular coated dehumidifier Technical Field

[0001] This utility model relates to the field of air conditioning dehumidification technology, specifically to a split-type modular coated dehumidifier. Background Technology

[0002] The principle of adsorption coating dehumidification is to coat the surface of the heat exchanger with a regenerable adsorption desiccant. The refrigerant inside the heat exchanger carries away the adsorption heat from the inner core and lowers the temperature of the dehumidification material for adsorption and dehumidification. The refrigerant inside the heat exchanger also heats the dehumidification material from the inner core for desorption and regeneration.

[0003] In the prior art, such as the utility model patent with application number CN202121048631.2, an integrated finned tube coating dehumidifier unit is disclosed. The unit space is divided by a partition, and unidirectional fans are installed in the air supply chamber and the air return chamber respectively. Two sets of finned tube coating heat exchangers are installed in the heat exchange chamber. The exhaust port and fresh air port are connected to the outdoor air, and the air supply port and the air return port are connected to the indoor air duct or air conditioner. The cooling water inlet and outlet pipes are connected to the cooling water supply device, and the regenerated hot water inlet and outlet pipes are connected to the hot water supply device. The continuous and stable operation of the dehumidifier unit is ensured by the conversion between dehumidification and regeneration through the two sets of finned tube coating heat exchangers.

[0004] To achieve continuous dehumidification, the aforementioned dehumidifier unit uses two sets of finned tube coated heat exchangers for alternating dehumidification and regeneration, which is costly, involves many valve components, and is complex to operate and control, resulting in decreased equipment reliability. However, when applied to basements, warehouses, or other cavernous environments where continuous dehumidification is not required, the equipment will operate intermittently, leading to poor economic efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a split-type modular coating dehumidifier that can meet the requirements of intermittent dehumidification, with fewer components, simpler control, and better economy, thereby solving the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The split-type modular coating dehumidifier includes an indoor unit and an outdoor unit. The indoor unit includes a casing, with a dehumidification air inlet valve and a regeneration air inlet valve installed at one end of the casing and a regeneration air outlet valve and a dehumidification air outlet valve installed at the other end. A processing fan and an adsorption coating heat exchanger are installed sequentially along the airflow direction inside the casing. The outdoor unit is equipped with a heat pump unit, and the adsorption coating heat exchanger is connected to the heat pump unit through a refrigerant pipeline.

[0008] As a further improvement, the regeneration air inlet valve and the regeneration air outlet valve are respectively connected to the outside via pipelines.

[0009] As a further improvement, a first partition and a second partition are fixedly installed inside the chassis along the airflow direction. The first partition and the second partition divide the inner cavity of the chassis into a first chamber, a second chamber, and a third chamber arranged sequentially along the airflow direction. The dehumidification air inlet valve and the regeneration air inlet valve are both connected to the first chamber, and the regeneration air outlet valve and the dehumidification air outlet valve are both connected to the third chamber. The processing fan is installed on one side of the first partition located inside the second chamber, and the adsorption coating heat exchanger is fixedly installed on one side of the second partition located inside the third chamber. Ventilation openings are respectively provided at the corresponding positions of the first partition and the processing fan, and at the corresponding positions of the second partition and the adsorption coating heat exchanger.

[0010] As a further improvement, a water receiving tray is fixedly installed in the third chamber below the adsorption coating heat exchanger.

[0011] As a further improvement, a dehumidifying air inlet filter is fixedly installed on the inner wall of the first chamber at a position corresponding to the dehumidifying air inlet valve; a regeneration air inlet filter is fixedly installed on the inner wall of the first chamber at a position corresponding to the regeneration air inlet valve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This application switches the operating states of the adsorption coating heat exchanger and the auxiliary heat exchanger of the outdoor unit. The adsorption coating heat exchanger acts as a condenser, the auxiliary heat exchanger acts as an evaporator, and the heat pump unit provides heating, which causes the adsorption coating heat exchanger to desorb and regenerate. Alternatively, the dehumidification heat exchanger acts as an evaporator, the auxiliary heat exchanger acts as a condenser, the heat pump unit provides cooling, and the adsorption coating heat exchanger cools and absorbs moisture, thereby meeting the needs of intermittent dehumidification at a lower cost.

[0014] This application has multiple working modes, including full return air dehumidification, mixed fresh air dehumidification, 100% fresh air dehumidification, and heating humidification, which can meet different usage needs;

[0015] Since the heat pump unit is located outdoors, the condensation heat during the regeneration and dehumidification periods of the adsorption coating heat exchanger is discharged outdoors, making this application more suitable for occasions that require dehumidification and cooling at the same time.

[0016] This application filters the air entering the chassis using a dehumidifying air intake filter and a regenerating air intake filter, making its functions more comprehensive. Attached Figure Description

The frame is welded from angle steel or square steel, or assembled from aluminum alloy profiles. The bottom plate, top plate, and end plates are fixed to the frame with self-tapping screws. The side plates are detachably installed on the frame by means of bolts, clips, etc., which facilitates the removal of the side plates for inspection of the inside of the casing 15.

Ventilation openings are provided at corresponding positions on the first partition 16 and the processing fan 6, and at corresponding positions on the second partition 17 and the adsorption coating heat exchanger 7, allowing air to circulate within the casing 15. Driven by the processing fan 6, air enters the casing 15 through the dehumidification inlet valve 2 or the regeneration inlet valve 3, undergoes heat and moisture exchange through the adsorption coating heat exchanger 7, and is then discharged through the regeneration outlet valve 10 or the dehumidification outlet valve 11.

[0027] In addition, a water collection tray 12 located below the adsorption coating heat exchanger 7 is fixedly installed in the third chamber 20 by fasteners. The water collection tray 12 is connected to a water outlet pipe extending to the outside of the casing 15, which facilitates the collection of condensate formed by the adsorption coating heat exchanger 7 during refrigeration and dehumidification.
