- Process air is heated (F to I, 14.5 ° C) o and further heated by the second reheating coil 7 (I to J, 16 ° C) and supplied to the room M Is done.
- the temperature / humidity state of the air changes as indicated by the solid line connecting points A and ⁇ [in FIG.
- the vaporizing humidifier on the upstream side of the cooling and heating coil, the temperature of the return cold water can be lowered and returned to the refrigerator.
- the dew condensation water generated by cooling and dehumidification and the waste water for continuous removal of odor and water-soluble gas components are at a low temperature. Since it can be used effectively as pre-cooling to the air side, a further excellent energy saving effect can be obtained.
- the cold water and return cold water as shown in FIG.
- the “simultaneous supply method” to flow in parallel to multiple coils, or use the “optimum selection method” as shown in Fig. 14 in which cold water and return cold water are in parallel in opposite flow and control is divided.
- a heating device is incorporated in the CRS system that supplies the cooling and heating coil and the reheating coil.
- the second cooling and heating coil Heating means 30 are provided in each of the return chilled water supply line 12 for supplying chilled water to 3b and the reheat coil side return chilled water supply line 18 for supplying chilled water to the reheat coil 6.
- the air conditioning system of the present embodiment having the above-described configuration, even when the temperature of the return cold water is low or the amount of the return cold water is small, even if the cooling and heating coils are provided in multiple stages, the humidification amount It is effective when there is a shortage.
- the present invention is not limited to the above-described embodiments, and the vaporizing humidifier is not limited to a hydrophilic or water-absorbing film.
- the vaporizing humidifier is formed by the latent heat of vaporization accompanying humidification, such as a water spray. As long as the dry-bulb temperature of the target air decreases, it is sufficient. Further, the presence or absence of the fan and filter is not particularly limited as long as it is not an essential constituent element of the present invention.
- the water supply method for the vaporizing humidifier can be either a circulating dripping method or a one-pass method (excess drainage).
- the quality of the water supply can be either brine or pure water.
- the water spray system is adopted as the most upstream side vaporizing humidifier, so that it is possible to operate even in winter-1 (severe cold season). . If only the temperature and humidity are targeted, the humidifier unit may be operated only during the winter humidification period.
- the heating device may be shared, and the return chilled water supply line 12 and the reheating coil side return chilled water supply line 18 system may have the same temperature.
- the capacity of the heating device may be increased and the heating coil 5 and the second reheating coil 7 may be unnecessary.
