Embodiment Construction

[0035] combined with figure 1To further describe the technical solution of the present invention, the device includes two sub-parts, that is, a dehumidification wheel and its regeneration part, a refrigeration unit and a radiant cooling part. The specific connection method is as follows: Dehumidification rotor and its regeneration part: the outdoor fresh air exchanges heat with the lower temperature exhaust air from the air-conditioned room in the air-air heat exchanger 4, and performs preliminary cooling and dehumidification, and then enters the dehumidification rotor. The wheel 1 further dehumidifies to meet the design humidity requirements. At the same time, the fresh air with a higher temperature enters the surface cooler 7 for isohumidity cooling. After reaching the design temperature requirements, it enters the room for replacement ventilation. With the rotation of the dehumidification wheel 1, the moisture absorption in the dehumidification area gradually reaches satura...

Abstract

The invention discloses a rotating wheel moisture removal and cooling-plate radiation cooling combined air conditioning system and an air conditioning method thereof. The device comprises a rotating wheel moisture removing part and a cooling-plate radiation cooling part. A moisture-removing rotating wheel is used for removing the moisture load of the fresh air supplied to rooms, and then dry fresh air is supplied to air-conditioner rooms in a replacement ventilation mode; the cold medium generated by a refrigerating unit serves as the cold medium for the radiation cooling of an indoor cooling plate, and the radiated cold energy is used for removing the moisture and heat load in the rooms. The fresh air is supplied to the air-conditioner rooms in the replacement ventilation mode to keep the freshness of indoor air; meanwhile, the indoor air flow rate is low, so the blown feeling of the human body is eliminated, the majority of the cold load is eliminated by radiation heat exchange, the indoor temperature distribution is uniform and thus the indoor comfort degree is improved obviously. In the system, the moisture removal and cooling of an indoor environment are combined, both the indoor temperature and humidity are controlled accurately, and the indoor air quality is improved; meanwhile, due to the independent control of the humidity, the efficiency of a refrigerating unit is improved and energy is saved.

Description

Technical field: [0001] The invention belongs to the technical field of energy utilization and energy saving, and relates to air dehumidification and radiation cooling technology, in particular to a composite air-conditioning system of dehumidification by a runner and radiation cooling by a cold plate. Background technique: [0002] With the continuous increase of the total number of buildings and the improvement of people's living standards, the proportion of building energy consumption in the total energy consumption has been increasing, and it has become the three major areas of energy consumption in my country along with industrial energy consumption and transportation energy consumption. The requirements for residential comfort are constantly increasing, and the application of air conditioning systems is becoming more and more common. The energy consumption of air conditioning accounts for an increasing proportion of building energy consumption. Therefore, in order to ac...
