Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of the humidifier. Reference numeral 1 denotes a humidifying dish which covers the outer periphery with a heat insulating material 2 and stores water inside. The humidifying tray 1 has a water supply port 3 on the upper portion of the side wall. As shown in FIG. 2, the water supply port 3 has a strainer 5 and a solenoid valve 6 and a water supply pipe having a cock 4 such as a tap for water supply (not shown). No)). A valve of the water supply port 3 is opened / closed by a ball tap 7 to keep the water level in the humidifying dish 1 constant. Water is filtered through the strainer 5 and supplied to the humidifying dish 1. The solenoid valve 6 opens the valve during heating to supply water to the humidifying tray 1, and closes the valve during cooling to stop water supply.

Reference numeral 8 is a heating pipe made of a material having good heat conductivity such as a copper pipe, and the lower half portion is immersed in water 9 stored in the humidifying dish 1. Reference numeral 10 is a water absorbent cloth having a high water absorbing property such as cotton cloth, which covers the heating pipe 8 exposed from the water surface, and both ends of the water absorbent cloth 10 are immersed in the water 9 of the humidifying dish 1.

Reference numeral 20 denotes a drain port provided at the bottom of the humidifying tray 1,
The overflow pipe 21 is fitted into this. When the water level of the humidifying tray 1 rises above the upper end of the overflow pipe 21, it is drained to the outside through the overflow pipe 21 and the drain port 20. Reference numeral 22 is an air vent valve for venting the air that has entered the heat exchanger 11.

In the case of a fan coil unit using hot water as the heat medium, the heating pipe 8 is connected to the inlet side of the heat exchanger 11 so that the hot water as the heat medium passes through the heating pipe 8 and then the heat exchanger 11 Pass through. (FIG. 3) In the case of an air conditioner that uses the refrigerant hot gas as a heat medium, the heating pipe 8 is connected to the refrigerant liquid outlet of the heat exchanger 11, and the refrigerant hot gas passes through the heat exchanger 11 and then the heating pipe 8. Pipe as shown in Fig. 4.

In the case of using a refrigerant hot gas as a heat medium such as an air conditioner, since the latent heat (condensation heat) is used, the temperature difference between the inlet and the outlet of the heat exchanger 11 is smaller than that in the case of hot water. Therefore, the temperature of the heating pipe does not decrease even after heating the air in the heat exchanger 11, but the temperature difference between the inlet and the outlet of the heat exchanger 11 is large in the case of using hot water as the heat medium. Therefore, in the case of the fan coil unit and the case of the air conditioner, the position of the heating pipe 8 connected to the heat exchanger 11 is reversed as described above.

Further, when the refrigerant hot gas passes through the heat exchanger 11 and then through the heating pipe 8 (FIG. 4),
There is an advantage that not only the flow control valve of the heat medium and the opening / closing valve at the time of cooling are not required, but also the heating pipe 8 plays a role of a cooling pipe at the time of cooling to increase the cooling capacity.

FIG. 5 is a vertical cross-sectional view of the humidifier 12 of the present invention assembled in a floor-standing fan coil unit 13. The floor-standing fan coil unit 13 is a rectangular casing covered with a metal panel and has an air outlet 14 on the upper surface. There is an air intake port 15 in the lower part of the front face, and an air filter 16 is attached above the air intake port 15. A blower 17 is attached above the air filter 16. A guide plate 18 adjusts the direction of the air from the blower 17. Humidifier 12
Is fixed so that it faces the blower side of the blower 17. And
The heat exchanger 11 is placed between the air outlet 14 and the blower 17.

When the floor-standing fan coil unit 13 is operated, hot water passes from the heating pipe 8 through the heat exchanger 11. The inside of the heating pipe 8 warms and evaporates the water of the humidifying dish 1 and the water absorbing cloth 10. The air is warmed by the heat exchanger 11, blown by the blower 17, and blown out from the air outlet 14. Along with the blowing by the blower 17, the steam generated by the humidifier 12 is also blown out from the air outlet 14.

FIG. 6 is a side sectional view of the humidifier 12 of the present invention incorporated into a ceiling fan coil unit 19.
The ceiling fan coil unit 19 has a rectangular housing shape covered with a metal panel, and has an air outlet 14 on the front surface at the left end in the drawing. An air filter 16 is provided on the rear surface at the right end in the drawing, and the surface to which the air filter 16 is attached also serves as an air intake port. An air blower 17 that blows air toward the front is attached to the front of the air filter 16. The heat exchanger 11 is placed between the air outlet 14 and the blower 17, and the humidifier 12 is fixed slightly below the heat exchanger 11.

Like the floor-standing fan coil unit 13, the ceiling fan coil unit 19 also blows steam along with warm air from the air outlet 14. However, unlike the floor-standing fan coil unit 13, the ceiling fan coil unit 19 can have the humidifier 12 installed in parallel on the downstream side of the air of the heat exchanger 11, and the high temperature air warmed by the heat exchanger 11 passes therethrough. The evaporation temperature rises and the amount of water evaporation increases accordingly.

The following is an actual measurement of the capacity of the humidifier in the case of the floor-standing fan coil unit 13 described above.
Here, the temperature and humidity outside the room are 0 ° C. and 40%, and the room is warmed to 20 ° C. and 50%. The heating pipe 8 is a copper pipe having an outer diameter of 22.23 mm and a length of 95 cm. The area of the water absorbing cloth 10 covering the heating pipe 8 is 0.039 square meters, and the water surface area of the humidifying dish 1 is 0.044 square meters.

Under the above conditions, the heating pipe 8 and the heat exchanger 1
Pour hot water with a temperature of 45 ° C into 1 and heat air etc.
It shall be 0 ° C. Heating capacity 1900 kcal / h
Then, the humidification load is about 0.12 kg / h for the amount of evaporated water and about 70 kcal / h for the amount of heat.

The amount of water evaporated from the humidifying tray 1 is 1.5 at a water surface temperature of 39.9 ° C.
Since it is 159 kg / h, it becomes 1.5159 × 0.044 = 0.0667 (kg / h). As for the amount of evaporated water of the water absorbent cloth 10, the surface temperature of the water absorbent cloth 10 is 42.1 ° C. and the amount of evaporated water per square meter is 1.7.
Since it is 513 kg / h, it becomes 1.7513 × 0.039 = 0.0683 (kg / h). Therefore, the total amount of evaporated water is 0.0667 + 0.0683 = 0.1350 (kg /
h). Therefore, the humidification load is increased by 12.5%.

Since the amount of heat of humidification is 108.0 kcal / h, the required flow rate of hot water is (the amount of heat of humidification + the amount of heat of heating).
/ Because of the temperature difference, (108 + 1900) / (45-40) = 401.6 (liter / h). Therefore, since 108 / 401.6 = 0.27, the temperature of the hot water for humidification and heating is lowered by only 0.27 ° C. by the humidifier.

As yet another embodiment, in the floor-standing fan coil unit 13, hot water having a temperature of 55 ° C. is caused to flow through the heating pipe 8 and the heat exchanger 11 to heat it to 48 ° C. after heating air or the like. Assuming that the heating capacity is 2700 kcal / h, the humidification load is 0.171 kg / h for the amount of evaporated water and about 100 kcal / h for the amount of heat.

The amount of water evaporated from the humidifying dish 1 is 2.3 at a surface temperature of the humidifying dish 1 of 47.2 ° C. and 2.3 per square meter.
Since it is 636 kg / h, it becomes 2.3636 × 0.044 = 0.1040 (kg / h). As for the amount of evaporated water of the water absorbent cloth 10, the surface temperature of the water absorbent cloth 10 is 50.5 ° C. and the amount of evaporated water per square meter is 2.8.
Since it is 410 kg / h, it becomes 2.8410 × 0.039 = 0.1108 (kg / h). Therefore, the total amount of evaporated water is 0.1040 + 0.1108 = 0.2148 (kg /
h). Therefore, the humidification load is increased by 25.6%.

Since the amount of heat of humidification is 166.5 kcal / h, the required flow rate of hot water is (166.5 + 2700) / (55-48) = 409.5 (liter / h). Therefore, 166.5 / 409.5 = 0.4, and the temperature of the hot water drops only 0.4 ° C. by the humidifier.

In any of the above cases, the heat quantity of humidification is
It is about 5 to 6% of the heating energy, and the increase of the heat source required for humidification is small.

As shown in FIG. 7, when the overflow pipe 21 is removed during cooling, water does not collect in the humidifying tray 1, and it can be used as a drain tray to simplify the equipment structure.

Furthermore, since the water absorbent cloth 10 is easy to put on and take off,
Remove when not heating. Further, since the water absorbent cloth 10 is relatively inexpensive, it may be replaced if the water absorbent cloth 10 becomes dirty or moldy.

In any of the above embodiments, the humidifier 12
Although it is provided on the blower side of the blower 17, it may be provided on the intake side. If the humidifier 12 is installed at a position facing the air flow path of the blower 17, the steam generated by the humidifier 12 will be generated by the blower 1
It blows out toward the room by 7.
