Heat storage type radiation air conditioning system employing heat pump air-conditioner

Abstract

A container material sealing and containing a latent heat storage material is arranged in a ceiling blow chamber box. Then, an air conditioning system of radiation type in which the metal panel is cooled or warmed by using as an auxiliary heat source the latent heat storage material having been cooled or warmed by heat storage achieved by cooling or warming the latent heat storage material with cool or warm air generated by a heat pump air-conditioner and then coolness or warmth is radiated from the metal panel into a room and an air conditioning system of convection type in which cool or warm air generated by the heat pump air-conditioner is blown into the room are provided and then the two air conditioning systems are used simultaneously or alternatively any one alone of the air conditioning systems is used so that air conditioning of the room is performed.

1 . A heat storage type radiation air conditioning system employing a heat pump air-conditioner, wherein one or a plurality of ceiling blow chamber boxes that are connected through a duct to an indoor unit installed in a room and linked to an outdoor unit of a heat pump air-conditioner through refrigerant piping and that are installed in a ceiling lower face are constructed such that a cover plate is fixed to and covers an upper opening part thereof and such that a metal panel provided with a large number of air flow holes punched and used for blow of cool or warm air and radiation of coolness or warmth is fixed to a lower opening part thereof, wherein a container material sealing and containing a latent heat storage material is installed inside the chamber box, and wherein an air conditioning system of air convection type in which cool air or warm air generated by the outdoor unit is blown through the indoor unit into the chamber box and then blown into the room through the large number of air flow holes of the metal panel and an air conditioning system of radiation type in which the metal panel is cooled or warmed by using as an auxiliary heat source the latent heat storage material having been cooled or warmed by heat storage achieved by cooling or warming the latent heat storage material with the cool air or the warm air from the outdoor unit and then coolness or warmth is radiated from the metal panel into the room are provided and then the two air conditioning systems simultaneously or alternatively any one alone of the air conditioning systems is allowed to be used. 
     
     
         2 . The heat storage type radiation air conditioning system employing a heat pump air-conditioner, wherein the latent heat storage material according to  claim 1  is composed of polyethylene glycol or paraffin which is a compound whose phase transition is achievable and which has a latent heat storage property. 
     
     
         3 . The heat storage type radiation air conditioning system employing a heat pump air-conditioner, wherein the container material according to  claim 1  is formed in in a bag shape by using an aluminum sheet, an aluminum film, polyethylene resin, polyethylene terephthalate resin, polyvinyl chloride, or nylon or alternatively is formed in a thin box shape by using a thin aluminum plate or polyethylene resin. 
     
     
         4 . The heat storage type radiation air conditioning system employing a heat pump air-conditioner, wherein the chamber according to  claim 1  has a size of 5 to 10 times the volume of the container material.
