ROTARY WHEEL HUMIDITY REGULATION DEVICE, AIR CONDITIONING SYSTEM HAVING SAME, AND CONTROL METHOD THEREFOR AND CONTROLLER THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/156239
Kind Code:
A1
Abstract:
A rotary wheel humidity regulation device, an air conditioning system having same, and a control method therefor and a controller thereof. The rotary wheel humidity regulation device comprises: an adsorption-type rotary wheel (1), with an outdoor exhaust pipe (EA), an indoor air supply pipe (SA) and an air supply connecting pipe (SA1) being arranged on the adsorption-type rotary wheel (1), and the air supply connecting pipe (SA1) being in communication with the indoor air supply pipe (SA) via the adsorption-type rotary wheel (1); an outdoor fresh air pipe (OA), with a first branch pipe (OA1) of the outdoor fresh air pipe (OA) being in communication with the outdoor exhaust pipe (EA) via the adsorption-type rotary wheel (1), and a second branch pipe (OA2) of the outdoor fresh air pipe (OA) being in communication with the air supply connecting pipe (SA1) via a first control valve (6); and an indoor air return pipe (RA) in communication with the air supply connecting pipe (SA1) via a second control valve (7); and heaters (2, 3) arranged on the first branch pipe (OA1) and/or the air supply connecting pipe (SA1). The rotary wheel humidity regulation device can switch between fresh air humidification and return air humidification according to indoor and outdoor humidity so as to solve the technical problem of reduced humidification capacity under low-humidity outdoor conditions, and switch between fresh air dehumidification and return air dehumidification so as to solve the technical problem of a poor dehumidification effect under high-humidity indoor conditions.
