Next, the air conditioner shown in FIGS. 5 and 6 will be described. 5 and 6, the same components as those described above are denoted by the same reference numerals, and description thereof will be omitted.

Referring to FIGS. 5 and 6, the air conditioner 1 includes a negative ion generator 3,
In addition to the humidifier 4 and the dehumidifier 5, an air heater 45 as a heating unit and an air cooler 46 as a cooling unit are further provided. The air heater 45 and the air cooler 46 are disposed downstream of the air inlet 8 and upstream of the humidifier 4 in the direction in which the air passes through the casing 2. The air coolers 46 are provided in parallel with the air passage direction so as to be arranged on the upstream side. FIG.
As shown in FIG. 1, in this air conditioner 1, the air intake 8 as the lower opening is formed by the front wall 17 of the casing 2.
The air outlet 6 as an upper opening is also provided on the front wall 17 of the casing 2.
Is formed in a rectangular shape extending in the width direction. A lattice-shaped louver 55 is attached to the air outlet 6, and the air outlet 6 and the upper opening side of the negative ion generator 3 are connected by an exhaust air duct 54.
Thus, the air that has passed through the negative ion generator 3 is blown out from the exhaust-side air duct 54 through the louver 55. A partition plate 57 is provided between the upper and lower sides of the air heater 45 and the air cooler 46 in the casing 2 and the lower side of the air heater 45 and the air cooler 46.

As the air heater 45, a finned coil type is used and is not shown in FIGS. 5 and 6, but inside the air 6 heater 45, a heating coil having many fins is provided. By supplying hot water to the heating coil from a hot water supply pipe 48 and discharging the hot water from a hot water discharge pipe 47, hot water is circulated, and heat exchange between the hot water heat medium and air is performed. The passing air is warmed. The hot water discharge pipe 47 is provided with a third control valve 49 for adjusting the amount of water supplied to the air heater 45.

The air cooler 46 is also of a coil type with fins and is not shown in FIGS. 5 and 6, but is provided inside the air cooler 46 in the same manner as the air heater 45. A cooling coil having a number of fins is provided, and the cooling coil is supplied with chilled water from a chilled water supply pipe 51 and discharged from a chilled water discharge pipe 50, thereby circulating the chilled water to form a chilled water refrigerant and air. By exchanging heat, the passing air is cooled. In addition,

The recess 40 is provided with a temperature sensor 53, and the third control valve 49 and the fourth control valve 52 are controlled by the control unit 42 based on the temperature detected by the temperature sensor 53. Thus, the temperature is always adjusted to a suitable temperature.

More specifically, for example, control as shown in the flowchart of FIG. 7 is performed. This control is performed by executing a temperature control program stored in the ROM of the control unit 42. In this temperature control program, an upper limit value _TH (for example, 25 ° C.) and a lower limit value _TL (for example, 20 ° C.) are set in advance as set temperatures. The upper limit value _TH and the lower limit value _TL are:
It is set arbitrarily according to the season and the like.

[0046] When the temperature control program is started, first, whether the detected temperature T _D which is detected by the temperature sensor 53 is lower than the lower limit T _L of the set temperature is determined (S2
1) If it is low (S21: YES), the fourth control valve 52 is closed (S22) and the third control valve 49 is opened (S23). As a result, warm water circulates in the air heater 45, and the air passing through the air heater 45 is heated. Then, the detected temperature T _D is equal to or lower limit T _L, or above or higher or not also is determined (S24), if the detected temperature T _D becomes the lower limit T _L or more temperature (S24: YES ), The third control valve 49 is closed (S25). Incidentally, if the detected temperature T _D is lower than the lower limit T _L (S24: NO)

5 is maintained.

[0047] Then, when the detected temperature T _D is higher than the lower limit T _L of the set temperature,: the (S21 NO) is then detected temperature T _D is higher than the upper limit value T _H of the set temperature Is determined (S26), and if high (S26: YE)
In S), the third control valve 49 is closed (S2).
7), the fourth control valve 52 is opened (S)
28). Thereby, the cold water circulates in the air cooler 46, and the air passing through the air cooler 46 is cooled. Then, the detected temperature T _D is equal to or upper limit value T _H, or whether it is lower than it is determined (S2
9), if the detected temperature T _D is equal to or less than the upper temperature limit T _H (S29: YES), the fourth control valve 52 is closed operation (S30). Incidentally, if the detected temperature T _D is higher than the upper limit value T _H (S29: NO), the opened state of the fourth control valve 52 is continued, cooling by air cooler 46 is maintained.
