Description

Integrated modular coated dehumidifier Technical Field

[0001] This utility model relates to the field of air conditioning dehumidification technology, specifically to an integrated modular coating 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 dehumidifying material to achieve dehumidification. The refrigerant inside the heat exchanger also heats the dehumidifying material from the inner core to achieve 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 dehumidification 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 an integrated modular coating dehumidifier that can meet the requirements of intermittent dehumidification. The device has fewer parts, is simpler to control, and is more economical, thereby solving the defects mentioned in the background art.

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

[0007] An integrated modular coated dehumidifier includes a cabinet. The upper part of the cabinet has a dehumidification chamber, and the lower part has a heat exchange chamber. An adsorption coating heat exchanger is fixedly installed in the dehumidification chamber. A treatment air inlet valve and a regeneration air inlet valve connected to the dehumidification chamber are installed on one side wall of the cabinet, and an air supply valve and an air exhaust valve connected to the dehumidification chamber are installed on the other side wall of the cabinet. A heat pump unit is located in the heat exchange chamber, and the adsorption coating heat exchanger is connected to the heat pump unit through a refrigerant pipeline.

[0008] As a further improvement, an air inlet box and a water collection tray are fixedly installed in the dehumidification chamber. The heat exchange chamber is located below the air inlet box and the water collection tray. The bottom of the air inlet box and the bottom of the water collection tray together separate the dehumidification chamber and the heat exchange chamber. The adsorption coating heat exchanger is fixedly installed in the water collection tray. The treatment air inlet valve and the regeneration air inlet valve are both connected to the air inlet box. An air outlet is provided on one side wall of the air inlet box, facing the adsorption coating heat exchanger.

[0009] As a further improvement, a partition is fixedly installed in the dehumidification chamber, the adsorption coating heat exchanger and the air outlet are both located on the same side of the partition, the air supply valve and the air exhaust valve are both located on the other side of the partition, and a processing fan is installed on the partition to drive air to flow towards the air supply valve and the air exhaust valve.

[0010] As a further improvement, a temperature and humidity sensor is installed on the side of the adsorption coating heat exchanger away from the air outlet.

[0011] As a further improvement, ventilation holes are provided on the side wall of the heat exchange chamber.

[0012] As a further improvement, a vent is provided on one side of the heat exchange chamber, and a mesh screen is fixedly installed on the cabinet to cover the vent.

[0013] As a further improvement, a fan is installed in the heat exchange chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This application switches the operating states of the adsorption coating heat exchanger and the auxiliary heat exchanger of the heat pump unit. The adsorption coating heat exchanger acts as a condenser and the auxiliary heat exchanger acts as an evaporator. Heating causes the adsorption coating heat exchanger to desorb and regenerate. Alternatively, the adsorption coating heat exchanger acts as an evaporator and the auxiliary heat exchanger acts as a condenser. The adsorption coating heat exchanger cools down and absorbs moisture, thereby meeting the needs of intermittent dehumidification at a lower cost.

[0016] This application has multiple working modes, including full return air dehumidification, mixed fresh air dehumidification, and 100% fresh air dehumidification, which can meet different usage needs;

[0017] This application achieves a higher degree of integration by placing the adsorption coating heat exchanger and the heat pump unit in the same cabinet.

[0018] The heat released by the auxiliary heat exchanger of the heat pump unit under dehumidification mode is discharged into the room, which can keep the indoor temperature basically stable. It is more suitable for occasions where the indoor temperature needs to be kept basically stable and only dehumidification is required. Attached Figure Description
