Abstract

The invention provides an active chilled beam. The active chilled beam comprises a shell body, an air inlet is formed in the bottom of the shell body, and air outlets are formed in the two sides of the shell body; the shell body is internally provided with air outlet channels and heat exchanging coils, wherein the air outlet channels and the heat exchanging coils communicate with the air outlets;and rotatable air guiding wing plates are arranged at the air outlets. On the one hand, the cooling load of all indoor areas is not required to be borne, and the active chilled beam only acts on the indoor specific guaranteed area, so that energy consumption is saved; and on the other hand, the size and the position of the indoor specific guaranteed area can be adjusted by changing the angles of the air guiding wing plates so that the indoor specific guaranteed area can be changed along with indoor personnel activities, and comfortableness is ensured. The invention further provides a chilled beam air conditioner system. The chilled beam air conditioner system comprises a natural energy collecting device and the active chilled beam; and water outlet pipes of the natural energy collecting device are connected with water inlets of the heat exchanging coils, and the natural energy collecting device is used for providing cold water to the heat exchanging coils. Natural energy resources canbe fully utilized to save energy, and the requirement of indoor thermal comfortableness is met.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment, in particular to an active chilled beam and a chilled beam air conditioning system. Background technique [0002] At present, building energy consumption occupies a high proportion in the total energy consumption of society, and HVAC energy consumption is the main part of building energy consumption. Therefore, it is necessary to reduce building energy consumption and achieve energy saving and emission reduction by optimizing the system and terminal form. The main body of the conventional active chilled beam is a cooling coil, through which the air is exchanged for heat. It is supported by shells on the left and right, similar to the beam installed on the top. After fresh air cooling and dehumidification treatment, it is sent to the static pressure box through the fan. Due to the entrainment effect of the fresh air, the indoor air is sucked in and cooled by the cooling coil, ...
