A ceiling device that enhances the heat exchange of the radiant cooling/heating roof plate

Abstract

The invention discloses a suspended ceiling device for reinforcing heat exchange of a radiant cooling / heating top plate. The suspended ceiling device mainly comprises a draught fan pressurization device, an indoor air inlet channel and positive pressure ventilation channels; the draught fan pressurization device is arranged at the top end of the indoor air inlet channel; and the positive pressure ventilation channels are located at the outer side of the indoor air inlet channel and communicate with the indoor air inlet channel through the draught fan pressurization device. Each positive pressure ventilation channel comprises a flow guide vane; the flow guide vanes are arranged at the rim of the bottom end of the suspended ceiling device, and the tail end of each flow guide vane is at a level angle; and the air-out ends of the flow guide vanes are closely adjacent to the radiant top plate. The suspended ceiling device aims at overcoming the defect that the radiant cooling / heating top plate is small in unit-area cooling / heating capacity; the suspended ceiling device for reinforcing heat exchange of the radiant cooling / heating top plate is simple in structure, convenient to mount, low in energy consumption and remarkable in effect; and meanwhile by means of the device, the problem that the radiant cooling surface is prone to dew formation can be effectively relieved and even eliminated.

Description

Technical field [0001] The invention relates to the field of design and manufacture of terminal devices of air conditioning systems, in particular to a ceiling device that enhances the heat exchange of a radiant cooling / heating ceiling. Background technique [0002] The energy consumption in the building sector in my country accounts for a considerable proportion of the total energy consumption in the country, and the proportion is approximately between one-fourth and one-third. In the building energy consumption, heating and air-conditioning energy consumption generally accounts for More than 50%, and with the continuous improvement of people's lives, this part of the energy consumption has a trend of continuous growth. Therefore, in the energy-saving and emission reduction work vigorously promoted at this stage in my country, the energy-saving of building heating and air-conditioning systems has important practical significance. Radiant cooling / heating technology is an HVAC tech...
