Description

Radiant Panel for Heating and Cooling and Heating and Cooling System Using the Same}

The present invention relates to a radiant panel for heating and cooling, in particular, a hollow or multi-porous air trap-shaped body is filled inside the panel, heated or cooled circulating air is used as a heat medium circulating inside the panel, and radiant heat based on the circulating air is used. The present invention relates to a radiant panel for cooling and heating, in which heat exchange of indoor air can be achieved by using the same, and a cooling and heating system using the same.

In general, in order to heat an indoor space, water heated by an electric heater or a boiler flows through a heating pipe installed on the floor to heat the floor. Such a heating system is widely used because it can simultaneously supply hot water for a shower and indoor heating using a single boiler.

However, such a heating system has a problem in that it takes a long time to heat the indoor space to an appropriate temperature because the floor is heated by hot water and the room is heated by the heated floor.

In addition, when the airtightness deteriorates due to deterioration of the building, it is difficult to maintain the temperature of the indoor space at a desired temperature due to cold wind entering from the outside.

In order to solve this problem, electric heaters or hot air fans are separately installed, but since these devices use electricity, oil, or gas to generate heat, they are difficult to handle and require high maintenance costs.

In addition, the hot air heater has a problem in that gases harmful to the human body are discharged while fuel is burned, so that the room must be ventilated frequently and heat loss occurs accordingly.

Recently, a radiant heating/cooling system that changes temperature using the principle of radiation rather than convection has been attracting attention, and the market share of the radiant heating/cooling system among all cooling/heating systems is steadily increasing.

Convection cooling and heating systems, such as air conditioners and heaters, cool or heat the indoor air and then use the principle of convection to control the overall indoor temperature, whereas radiant heating and cooling systems indirectly cool the indoor air by circulating cold or hot water. Or use the principle of heating.

The convection heating and cooling system has one body in the living room, and ducts for air circulation must be provided to perform cooling and heating in a plurality of rooms separated from the living room. increase, and the temperature distribution is non-uniform. In addition, there are problems in that a user feels uncomfortable due to excessive airflow and deteriorates an indoor living environment such as scattering of dust.

On the other hand, the radiant heating and cooling system uses water, which has a higher heat capacity than air, as a heat medium, so it is advantageous in terms of maintenance cost. That is, it is known that the heat transport energy is less than that of conventional air conditioners or fan heaters, and the indoor temperature can be kept relatively low or high to maintain the same level of comfort, thereby having a great effect on energy saving.

In addition, it has the advantage of improving the quality of indoor air with less noise and less fine dust or suspended matter in the air, and it is possible to maintain a constant humidity distribution as well as the temperature in the room, so that everyone from children to adults and the elderly can live comfortably. can provide a comfortable indoor environment. In addition, since the radiant heating and cooling system does not have the problems of noise and airflow that existing air conditioning equipment has, it is advantageous to apply to public facilities such as hospitals, libraries, laboratories, museums, cultural and artistic facilities, restaurants, as well as houses.

The radiant heating and cooling system is a cooling and heating system in which heating and cooling is performed through a radiant panel, and includes a radiant panel installed on a wall or ceiling, a boiler for supplying hot water, a refrigerator for supplying cold water, and a cooling and heating controller. Radiant panels are installed on walls or ceilings in a continuous matrix and have heat medium tubes inside. The boiler is connected to the heat medium tube to supply hot water, the refrigerator is connected to the heat medium tube to supply cold water, and the air-conditioning controller controls the operation of the boiler and the refrigerator so that cold water or hot water is selectively supplied to the heat medium tube. Such a radiant heating and cooling system is disclosed in Korean Patent Registration No. 10-1078605 (Patent Document 1).

In applying radiant heating and cooling systems to various buildings, the arrangement and installation of radiant panels are important. In order to increase indoor cooling and heating efficiency, radiant panels should be continuously arranged at regular intervals on walls or ceilings, and heat medium tubes should be stably connected to neighboring radiant panels. In addition, construction cost and construction time can be reduced when construction is convenient.

A radiant panel for heating and cooling is disclosed.

On the other hand, in Korean Patent Registration No. 10-1081669 (Patent Document 4), cold water or hot water circulating through the floor pipe installed on the floor above the slab circulates inside the lightweight concrete panel, as well as radiant cooling and heating by the floor layer, as well as lightweight concrete. Disclosed is a lightweight concrete panel having a radiant cooling/heating function in which wall radiant cooling or heating is performed by the panel and a local exhaust function, and a wall structure using the same.

The radiant panels for cooling and heating of Patent Documents 1 to 4 include a heat medium tube having a flow path through which the heat medium flows inside the panel, and control hot water or cold water from a boiler and a refrigerator to circulate through the heat medium tube using a cooling/heating controller. are doing

However, in the radiant panels for heating and cooling of Patent Documents 1 to 4, heat exchange is rapidly performed at the temperature in the air when the operation of the boiler and the refrigerator is stopped and the operation of the blower is stopped. As a result, the conventional radiant panel has a disadvantage in that it cannot emit radiant heat for a long time even after the operation of the boiler and the refrigerator is stopped by absorbing and storing high or low temperature heat medium when it circulates.

In addition, since the radiant panels for cooling and heating of Patent Documents 1 to 4 use water as a heat medium that circulates through the heat medium tube, convection cools or heats the air in the room quickly, such as in a convection type cooling and heating system such as an air conditioner or a warm fan, It is difficult to control the overall temperature. That is, the above-mentioned conventional radiant panels for cooling and heating have a problem in that they cannot quickly cool or heat indoor air at the initial stage of operation of the cooling and heating system or according to the user's needs.

Furthermore, in the case of a conventional radiant panel using water as a heat medium circulating through a heat medium tube, when the heat medium tube is a metal pipe, when used for a long period of time, the inside of the piping pipe is corroded or foreign matter accumulates to obstruct the flow of the circulated heat medium, resulting in low thermal efficiency or There is a problem in that water leakage occurs according to the damage of the plumbing pipe.
