Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating and cooling system that utilizes waste heat generated within a building to perform local air conditioning of rest areas (within parasols) in plazas and building premises. .

Conventional technology Usually, heating and cooling are not performed in outdoor spaces such as nosorasols and gazebos.

Problems to be Solved by the Invention Since heating and cooling outdoors, that is, in an open space, is extremely inefficient, it is necessary to realize local air conditioning at low cost.

Means to solve the problem An air conditioning wind pipe is formed using the fins of a heat pipe that applies capillary phenomenon, and air conditioning is performed by heating or cooling the air passing through the heat pipe. conduct.

As the heat source for the heat transfer pipe, the heat contained in the exhaust gas generated by the air conditioner inside the building is used.

action Exhaust air from buildings or machinery/equipment rings is supplied to the wind pipe.

By heating or cooling the lower heat exchange section of the heat transfer pipe with the exhaust air from the building's air conditioner, the air in the wind pipe in contact with the heat transfer pipe is blown into the parasol in a cooled or heated state.

Embodiment In FIGS. 1 to 7, 1 is a parasol, 2 is a heat medium pipe, 3 is a wind pipe formed by the fins 21 of the heat medium pipe 2,
4 is the outlet of the wind pipe 3, 5 is the pedestal and blower pipe, 6 is the suction port, 7 is the blower fan, 8 is the insulating material, 9 is the ceiling surface of the air conditioning room, 10 is the sky diagram in the ceiling, 2 -111 is an air-conditioned room, n is a finned heat recovery part at the bottom of heat medium pipe 2, vane is a wick placed inside heat medium pipe 2 and has a capillary action, and Sae is a cylinder placed inside wick B. It is a partition.

First, the structure and operating principle of the heat transfer pipe 2 will be explained.
As shown in Figure 7, a wick with capillary action such as carbon fiber or metal mesh is arranged around the cylindrical partition, and a working fluid such as water, Freon, or ammonia is sealed in the high vacuum tube. There is.

Now, when the right side (!2 condensation section) in Figure 7 is cooled, the vapor of the working fluid liquefies, and the liquid flows to the left side (evaporation section) due to the capillary action of the wick, absorbing heat from the outside and evaporating. do.

The steam passes inside the cylindrical partition and flows at high speed toward the condensation section where the steam pressure is low, where it releases latent heat of condensation and liquefies. The working fluid circulates to the evaporation section again by the capillary action of the wick n, absorbs the heat of evaporation, and is vaporized. This operation is repeated to perform heat recovery, ie, cooling, in the evaporator.

In the case of heating, the operation is reversed, that is, heating one end of the heat transfer pipe causes heat to be released from the other end.

Next, in FIGS. 1 to 6, the lower end of FIG. 1 (6) communicates with the heat source section of FIG. 5, and a blower fan 7 supplies air to the wind pipe 3. When the finned heat recovery section n is cooled, heat is absorbed above the heat transfer pipe 2 inside the parasol 1.

Air supplied to the wind conduit 3 by the blower fan 7 is cooled at the upper part of the heat transfer pipe 2, and is blown into the parasol 1 through the outlet 4. When the finned heat recovery section n is heated, hot air is blown out from the outlet 4 in the same manner.

In the above embodiment, air is blown into the wind conduit 3 by the blower fan 7, but surplus air from equipment in the building can be used.

Further, the number of heat medium pipes 2 to be used, the position and size of the air outlet 4, etc. are set depending on the required heating and cooling capacity.
