Description

  The present invention relates to a condensation-free heating system that prevents the occurrence of condensation and mold.

  For example, as shown in FIG. 3A, in a detached house 51 in which a Japanese-style room 53 and a living room 52 are provided on the first floor, these rooms 52 and 53 can be individually heated so that the living room 52 and the Japanese-style room 53 can be heated. It has been conventionally performed to install heat pump type air conditioners 54 and 55 in each of the above.

  However, in the detached house 51 as described above, when the air conditioner 54 in the living room 52 is frequently used but the air conditioner 55 in the Japanese-style room 53 is not often used, condensation occurs in the Japanese-style room 53 and mold grows in winter. May cause damage.

  In view of the conventional problems as described above, the present invention is provided with a heater in a plurality of indoor rooms so that each room can be individually heated. In winter, some rooms are heated. It is an object of the present invention to provide a condensation-free heating system that can prevent condensation and mold from occurring in a room that is not heated when performed.

  In order to clarify the cause of condensation and mold in the Japanese-style room 53 in the above-mentioned problem, the present inventor has conducted various investigations and experiments to identify the cause as follows. It came.

That is, if the living room 52 where the person is present is heated with the air conditioner 54 while the air conditioner 55 of the Japanese room 53 where there is no person is stopped, and the room temperature of the living room 52 is set to 20 ° C. and the relative humidity is 60 RH%, for example, humidity 8.8 g / m ^3, and the a diffusion phenomenon of water vapor, the absolute humidity of the Japanese-style 3 also became 8.8 g / m ^3. Therefore, if the room temperature of the unheated Japanese-style room 53 is 13 ° C., the relative humidity of the Japanese-style room 53 becomes a high humidity state of 95 RH%, which is the cause of condensation and mold in the Japanese-style room 53. It was.

The present invention has been made on the basis of the above-described cause elucidation, and the above-described problem is solved by a heating system in which a plurality of indoor rooms are provided with heaters and each room can be individually heated. In
A control means and a humidity sensor;
When some rooms are heating rooms and the remaining rooms are non-heating rooms, based on the signal from the humidity sensor of the non-heating room, the relative humidity of the non-heating room should not exceed the allowable value. The control for driving the heater is solved by a condensation-less heating system characterized in that the control means performs the control.

  In this heating system, when the relative humidity of the non-heating room becomes high due to heating in the heating room, it is detected and the heater of the non-heating room is driven. The relative humidity does not become higher than the allowable limit, so that it is possible to prevent condensation and mold from occurring in a room that is not heated. In addition, the allowable value of the relative humidity of the non-heating room for preventing the occurrence of condensation and mold is, for example, 80 RH%.

  In the above system, the driven heater of the non-heating room may be controlled so that the temperature of the non-heating room is kept lower than the temperature of the heating room. In this case, it is possible to prevent the occurrence of condensation and mold in the non-heating room, while keeping the energy cost required low, and to alleviate the heat shock between the heating room and the non-heating room. Can do.

  Since the present invention is as described above, a plurality of indoor rooms are equipped with heaters, and each room can be individually heated. In the winter, some rooms were heated. In this case, it is possible to prevent condensation or mold from occurring in a room where heating is not performed.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  The dew-less heating system of the embodiment shown in FIGS. 1 (a) and 1 (b) is used in a building 1 of a detached house, 2 is a living room as a heating room, and 3 is a Japanese room as a non-heating room. In each of the rooms 2 and 3, heat pump type air conditioners 4 and 5 are installed as heaters. A control device 6 for controlling the driving of the air conditioners 4 and 5 is provided, and the Japanese-style room 3 is provided with a humidity sensor 7, and a detection signal from the humidity sensor 7 is sent to the control device 6. . In addition, 8 is an entrance, 9 is a corridor, 10 is a dining room, 11 is a kitchen, 12 is a wash-dressing room, 13 is a bathroom, and 14 is a toilet.

  In the above heating system, as shown in FIG. 2 (a), when the temperature of the indoor 15 is 13 ° C. in winter, the air conditioner 4 in the living room 2 is driven while the air conditioner 4 in the Japanese room 3 is stopped. When the living room 2 is heated to a room temperature of 20 ° C. and a relative humidity of 60 RH%, the absolute humidity of the living room 2 rises in the process, and the absolute humidity of the Japanese room 3 by the diffusion of water vapor. As a result, the relative humidity of the Japanese-style room 3 increases.

  When the relative humidity reaches 80 RH%, which is an allowable value for condensation or mold, the humidity signal is sent from the humidity sensor 7 of the Japanese-style room 3 to the control device 6, and the air-conditioner 5 of the Japanese-style room 3 is controlled by the control device 6. The driving is started, the room temperature of the Japanese-style room 3 is raised, and the relative humidity of the Japanese-style room 3 is prevented from exceeding the allowable value of 80 RH%.

  And in this embodiment, when sending the drive start signal to the air conditioner 5 of the Japanese-style room 3, the control device 6 is also adapted to send the temperature setting signal of the Japanese-style room 3 together. A predetermined temperature, for example, 4 ° C lower than the set temperature of the air conditioner 4 is selected.

As a result, as shown in FIG. 2 (b), the living room 2 has a room temperature of 20 ° C. and a relative humidity of 60 RH%, and the living room 2 has an absolute humidity of 8.8 g / m ³ , which is caused by the diffusion phenomenon of water vapor. Even if the absolute humidity of the Japanese-style room 3 becomes 8.8 g / m ³ , the relative humidity becomes 78 RH% in the Japanese-style room 3 when the room temperature rises to 16 ° C. Is prevented. Moreover, in this embodiment, since the Japanese-style room 3 is heated to a temperature lower than the living room 2, the energy cost required to prevent condensation and mold generation in the Japanese-style room 3 can be kept low. Moreover, the heat shock between the living room 2 and the Japanese-style room 3 can be reduced.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described embodiment, the case where the temperature setting of the Japanese-style room 3 is performed by the control by the control device 6 is shown, but when the heating set temperature of the living room 2 is determined, the control by the control device 6 is not performed. In addition, the temperature setting function provided in the air conditioner 5 of the Japanese-style room 3 may be used to set the temperature in advance.

  In the above embodiment, the case where the living room 2 is a heating room and the Japanese room 3 is a non-heating room is described. However, a system configuration in which the Japanese room 3 is a heating room and the living room 2 is a non-heating room is adopted. Alternatively, a system configuration may be employed in which the living room 2 can be a heating room, the Japanese room 3 can be a non-heating room, the Japanese room 3 can be a heating room, and the living room 2 can be a non-heating room. Of course, not only living room 2 and Japanese room 3, but also living room and living room, Japanese room and Japanese room, and not limited to the relationship between two rooms, it is also possible to configure the system with a relationship between three or more rooms. It is.

  Furthermore, in the above embodiment, the case where the heater is a heat pump type air conditioner is shown. However, the heater may be a heater using gas or kerosene, or a floor heater using hot water or electricity. Or a heater. Further, the system of the present invention is not limited to a detached house, and can be used in each house of an apartment house such as a condominium, and can be widely used in various buildings such as office buildings.
