JP 2005-195319 A

  In the above-described conventional configuration, since the plurality of supported portions in one heat medium flow tube are supported by each of the plurality of floor support members, the supported portions in the heat medium flow tube are supported and heated. The location where the cooling action or heating action by the medium is exerted becomes dense in the direction in which the floor support members are arranged on the floor surface, and this is not preferred when the cooling load or heating load when cooling or heating is large. It becomes.

  However, when the cooling load or the heating load when performing cooling or heating is small, for example, the supply of the heat medium that circulates through the heat medium flow pipe is intermittently connected to the heat medium flow from the heat medium supply source. Even if the amount of heat given to the pipe is adjusted, the places where the cooling action or the heating action is exerted are densely present in the direction in which the floor support members are arranged on the floor surface. May be excessive.

  As a result, the conventional configuration has a disadvantage in that good cooling or heating cannot be performed when it is used in a situation where the cooling load or the heating load varies greatly.

  An object of the present invention is to provide a cooling / heating device that can perform favorable cooling or heating even when the cooling load or the heating load fluctuates greatly.

  In the cooling / heating apparatus according to the present invention, the heat medium flow pipes through which the cooling or heating heat medium supplied from the heat medium supply source circulates are arranged in parallel below the floor of the building in the horizontal direction. And a plurality of supported parts supported by the floor support member in a state along the longitudinal direction thereof, and a plurality of connection parts for connecting the adjacent supported parts to each other. The first characteristic configuration is arranged in a state where the supported portion is supported by every other or every plurality of the floor support members of the plurality of floor support members. A plurality of the heat medium flow tubes are provided in a state in which the floor support members to be supported are different from each other and allow the heat medium to flow in parallel, and each of the heat medium flow tubes is supplied with a heat medium. A heating medium supply state switching means capable of switching between a state in which the heating medium is supplied and a state in which the heating medium supply is stopped is provided. It lies in the fact that.

  According to the first characteristic configuration, the plurality of heat medium flow pipes are provided in a state of being supported by every other or every other floor support member of the plurality of floor support members, and the heat medium supply state The plurality of heat medium flow tubes can be switched by the switching means between a state in which the heat medium is separately supplied and a state in which the supply of the heat medium is stopped.

  When the cooling load or heating load when performing cooling or heating is large, the cooling medium or the heating action by the heating medium is exhibited by causing the heating medium to flow through each of the plurality of heating medium flow pipes. By making the location dense in the direction in which the floor support members are arranged, a large cooling load or heating load can be handled.

  On the other hand, when the cooling load or the heating load when performing cooling or heating is small, a part of the heat medium is caused to flow through only one part of the plurality of heat medium flow pipes. It is possible to exhibit the cooling action or the heating action by the heat medium only at the place corresponding to the floor support member in which the heat medium flow pipe is provided, and the place that exhibits the cooling action or the heating action by the heat medium is the floor support member. Therefore, the amount of heat for cooling or heating can be reduced so as to correspond to a small cooling load or heating load.

  That is, the heat medium supply state switching means switches the plurality of heat medium flow pipes between a state in which the heat medium is separately supplied and a state in which the heat medium supply is stopped, so that the heat medium flow from the heat medium supply source. The amount of heat for cooling or heating given to the pipe can be changed in a wide range.

  Therefore, according to the first characteristic configuration, it is possible to provide a cooling / heating device that can perform favorable cooling or heating even when the cooling load or the heating load fluctuates greatly.

In the second feature configuration of the present invention, in addition to the first feature configuration, the supported portion includes:
An outward path portion supported in a state extending along one lateral side surface of the floor support member from one end side to the other end side in the longitudinal direction of the floor support member; and on the other end side in the longitudinal direction of the floor support member A horizontal loop portion bent in a loop shape in plan view from the forward path portion toward the other lateral side surface of the floor support member, and from the other end side in the longitudinal direction of the floor support member toward the one end side.

In this state, the adjacent supported parts are connected to each other at the connection part, and a continuous heat medium flow path is formed.

  According to the second characteristic configuration, the heat medium flow pipe has a plurality of supported portions supported by the floor support member in a state along the longitudinal direction of the long floor support member, and the adjacent supported portions And a plurality of connection portions for connecting the two. And the supported portion supported by the floor support member is supported in a state extending along one lateral side surface of the floor support member from one end side to the other end side in the longitudinal direction of the floor support member; , In a loop shape in plan view from the forward path portion to the other lateral side of the floor support member via the lower side of the floor support member on the other end side in the longitudinal direction of the floor support member.

With. In addition, the supported parts adjacent to each other are arranged such that one end in the longitudinal direction of the return path part in one of the supported parts and one end in the longitudinal direction of the forward path part in the other supported part. The end portion on the side is connected by the connecting portion to form a continuous heat medium flow path. That is, the meandering heat medium flow path is formed in a state where a plurality of supported parts supported by the floor support member are connected to each other at the connection part and are connected in series.

  As described above, the supported portion in the heat medium flow pipe is provided along the longitudinal direction of the floor support member by the forward path portion, the horizontal loop portion, and the return path portion, and the longitudinal length of the floor support member. However, since the horizontal loop portion is formed in a state of being bent in a loop shape in plan view when it is folded, for example, under the floor support member. By using a wide space on the side or by using a wide space on both the left and right sides of the floor support member, it can be bent and folded in a large loop shape, and the bent portion can be bent with a large radius of curvature.

  As a result, even if the heat medium flow pipe is subject to thermal contraction due to switching between a state where the heat medium flows and a state where flow is stopped, and a temperature difference occurs, the heat medium flow pipe is bent with a large radius of curvature. For example, in a curved part that is bent, the amount of contraction can be absorbed by a slight change in the degree of bending. It becomes easy to avoid disadvantages such as occurrence.

  Therefore, according to the second characteristic configuration, it is possible to provide an air-conditioning / heating device in which the heat medium flow pipe is less likely to be damaged at an early stage and the heat medium flow supply can be satisfactorily performed over a long period of time.

  According to a third characteristic configuration of the present invention, in addition to the second characteristic configuration, the floor support member is provided in a state in which the floor supporting member has a vertically long cross-sectional shape having a width in the vertical direction wider than a width in the horizontal direction.

The floor board for constituting the portion is placed, and the floor support member and the floor board are connected and fixed by, for example, driving nails or bonding them with an adhesive. And since the forward path part and the return path part in the heat medium flow pipe are positioned and supported on the lower side of the lateral side surface of the floor support member, the floor plate is connected by a connector such as a nail as described above. When the assembly work for connecting the floor support member and the floor support member is performed, there is little risk that the connecting tool interferes with the heat medium flow pipe and damages the heat medium flow pipe.

  Therefore, according to the third characteristic configuration, there is provided an air conditioning apparatus capable of disposing the heat medium flow pipe in a state in which there is little risk of damaging the heat medium flow pipe due to the assembly work of connecting the floor plate and the floor support member. I was able to provide it.
