。BACKGROUND OF THE INVENTION Radiant heating and cooling systems are known as a method for achieving milder cooling than in the past. Conventional radiant heating and cooling equipment, especially for cooling, attaches a piping vibrator to the ceiling and circulates cold water through it, aiming to achieve cooling without the feeling of draft by allowing cool air to naturally fall inside the room. be.

充分に普及するものとはなっていなかった。Problems to be Solved by the Invention However, the problems with conventional radiant heating and cooling systems are:
The circulation of cold water on the ceiling surface removes only sensible heat from the indoor air, and if latent heat is also removed, dew condensation will occur on the ceiling surface. Therefore, with conventional radiant heating and cooling systems, a separate cooling system is required to remove latent heat from indoor air, especially during cooling, making the system complex and large-scale.
It was not widely used.

た輻射冷暖房装置を提供することを目的とする。The present invention is intended to solve the problems of conventional radiant cooling and heating systems, and specifically, it organically combines a radiant cooling system using a refrigerant and an air-type cooling system for removing latent heat. The purpose of the present invention is to provide a radiant cooling/heating device that is also capable of heating operation.

It is constructed by sequentially connecting a pressure reducing device and a load-side heat exchanger through piping, and arranging a solenoid valve in the piping that bypasses the radiant cooling heat exchanger.

の生じる危険を防止できるものである。In such a radiation cooling/heating system, when the solenoid valve in the bypass piping is opened at the start of cooling operation, the refrigerant that has passed through the compressor, four-way valve, and heat exchanger on the heat source side flows through the bypass piping, which has less resistance. The flow is reduced in pressure by a second pressure reduction device and acts as a cooling agent in the load side heat exchanger,
This makes it possible to remove latent heat from indoor air. After that, when the solenoid valve is closed, the refrigerant that has passed through the heat source side heat exchanger is depressurized by the first pressure reducing device and used for cooling in the radiant cooling heat exchanger, and is further depressurized by the second pressure reducing device to supply the load. Flows into the side heat exchanger. In this case, the radiant cooling heat exchanger and the load-side heat exchanger both act as evaporators, but the load-side heat exchanger has a lower evaporation temperature, and the load-side heat exchanger removes the latent heat of the indoor air. , it is possible to remove sensible heat from indoor air in a radiant cooling heat exchanger and achieve mild cooling. Therefore, for example, when a heat exchanger for radiant cooling is configured as a pipe vibrator attached to a ceiling surface, it is possible to prevent the risk of condensation water forming on the ceiling surface.

る。Conversely, during heating operation, if the solenoid valve in the bypass piping is opened, the refrigerant that has passed through the compressor, four-way valve, and load-side heat exchanger will be depressurized by the second pressure reducing device, and the bypass piping will have less resistance. is circulated and flows into the heat source side heat exchanger. Therefore, in this case, indoor air is heated in the load-side heat exchanger, and almost no refrigerant flows into the radiant cooling heat exchanger, making it possible to reduce energy consumption.

ルドな冷房を実現できるものである。In such a radiation cooling/heating system, during cooling operation, the solenoid valve 9 in the bypass pipe 8 is opened at the start of operation, and the refrigerant passes through the compressor 1, the four-way valve 2, and the heat source side heat exchanger 3.
It flows through the bypass piping 8 with low resistance, and the second pressure reducing device 6
The pressure is reduced by the fan (
(not shown) performs a cooling effect by exchanging heat with the indoor air, and first removes some latent heat from the indoor air. After that, when the electromagnetic valve 9 is closed, the refrigerant that has passed through the heat source side heat exchanger 3 is depressurized by the first pressure reducing device 4 and is provided for cooling in the radiant cooling heat exchanger 5, and is further passed through the second pressure reducing device 6. It is depressurized and flows into the load-side heat exchanger 7. In this case, the radiant cooling heat exchanger 5 and the load-side heat exchanger 7 both act as evaporators, but the load-side heat exchanger 7 has a lower evaporation temperature, and the latent heat of the indoor air is absorbed by the load-side heat exchanger 7. Radiant cooling heat exchanger 5 while removing
This makes it possible to remove sensible heat from indoor air. At this time, it is desirable to reduce the fan air volume of the load-side heat exchanger 7 as much as possible to remove moisture in the air. It removes the sensible heat from the indoor air on the ceiling surface without condensing water, and achieves mild cooling through the natural fall of cold air.
