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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a heat storage type radiation air conditioning system employing a heat pump air-conditioner, wherein a container material sealing and containing a latent heat storage material is arranged in a ceiling blow chamber box installed in the ceiling lower face, and wherein an air conditioning system of air convection type in which the cool air or warm air generated by the heat pump air-conditioner is blown into the chamber box so that air is blown into a room through a large number of air flow holes punched in a metal panel in the chamber box lower face and an air conditioning system of radiation type in which heat storage is achieved by cooling or warming the latent heat storage material with the cool air or the warm air generated by the heat pump air-conditioner so that the metal panel is cooled or warmed by using as an auxiliary heat source the latent heat storage material having been cooled...

AI Technical Summary

Benefits of technology

The present invention provides a heat storage type radiation air conditioning system that can effectively cool or heat a room using both air convection and radiation air conditioning systems. The system can also be used simultaneously to reduce power usage and electricity charges. Additionally, a latent heat storage material is used as an auxiliary heat source to reduce the temperature difference between the room temperature and the lowest blow temperature at cooling or the highest blow temperature at heating, and to reduce discomfort to the residents.

Problems solved by technology

Nevertheless, the lowest blow temperature at cooling is approximately 10° C. and the highest blow temperature at heating is approximately 40° C. That is, the blow temperature has an extremely large temperature difference form the room and hence causes discomfort to the residents.

Further, in winter, heating operation need be temporarily stopped for defrosting and this causes discomfort to the residents.

Nevertheless, even if this member is of a metal panel, the metal panel does not have a heat storage property.

Thus, the blow temperature becomes excessively low at cooling and excessively high at heating, and hence discomfort to the residents remains.

This causes a problem of increase in power usage and electricity charges.
