RADIANT AIR CONDITIONING SYSTEM

摘要

PROBLEM TO BE SOLVED: To keep an indoor environment comfortable and maintain a stationary air conditioning of radiation-convection parallel air conditioning in response to variation of indoor environment and fluctuation of indoor thermal load during heating operation in an air conditioning system wherein thermal radiation from a ceiling face and convection heat transfer are parallel is employed. SOLUTION: Indoor air sucked through an inlet 5a of an indoor machine is guided to an indoor heat exchanger 7 by an indoor fan (blower) 6 and is divided to a direct outlet 5b and a radiant duct 10 by a damper 9 and a room interior 11 is air-conditioned by radiant heat transfer from a radiant panel 10a and convective heat transfer. An outdoor temperature sensor 13 is installed in an outdoor machine, an indoor temperature sensor 14 is installed in the inlet 5a of the indoor machine and a radiant temperature sensor 15 and a panel temperature sensor 16 are installed in a ceiling 11a and these are connected to a stationary controller 12. The stationary controller 12 carries out a radiation-convection parallel stationary operation control of an air conditioning system at predetermined air-conditioning conditions.
