Abstract: In an air conditioner including an indoor heat exchanger and an indoor fan which are disposed in an indoor-side chamber, and an outdoor heat exchanger and an outdoor fan which are disposed in an outdoor-side chamber, the indoor-side chamber and the outdoor-side chamber being partitioned by a partition plate mounted on a bottom plate, the outdoor heat exchanger is disposed on said bottom plate, and the bottom plate is integrally formed with a dam member for damming up drain water flowing from at least one of the indoor heat exchanger and the outdoor heat exchanger.

Abstract: In an air conditioner (10) including an indoor-side chamber (21) containing an indoor heat exchanger (11) and an indoor fan (12), and an outdoor-side chamber (22) containing outdoor heat exchanger (13) and an outdoor fan (14), the indoor-side chamber (21) and the outdoor-side chamber (22) being partitioned by a partition plate (20), the partition plate (2) has a top panel (42) having a ventilation opening portion and a ventilation shutter (49) for opening/closing said ventilation opening portion (48) to freely adjust the opening degree of said ventilation opening portion (48). An indoor fan casing (34) having a heater lower-portion mounting portion (64) located above a drain pan (33) is provided between the indoor fan (12) and the partition plate (20), and an electrical heater (55) is disposed on the heater lower-portion mounting portion (64) so that the electric heater (55) is located above the drain pan (33) through the lower-portion mounting portion (64).

Abstract: When a single room unit 4 is connected to a compressor 2B of the outdoor unit 1, the room unit 4 is connected to a connection box 29 which is mounted on the outdoor unit 1. Instead, if two room units 5A and 5B must be connected to the outdoor unit 1, a connection box 37 is mounted on the back of the outdoor unit 1. The connection box 37 has branches each having valves 44A and 44B and expansion devices 43A and 43B. The two room units are connected to these branches of the connection box 37. Because of these optional connection boxes, the outdoor unit itself may be constructed in a compact form, and connection of multiple room units to the outdoor unit may be carried out conveniently and correctly in a simple manner.

Abstract: An ejector-type gas nozzle 17 including a liquid nozzle and a gas nozzle is used. Raw material water A in ozone reaction tank 1 is pumped and pressurized by pump 19 to use it circulatingly as water jet A of the ejector gas nozzle 17. The liquid nozzle of ejector-type gas nozzle 17 introduces the water jet A into the raw material water A in the ozone reaction tank 1. Ozone gas is sucked by negative pressure to be generated along the stream of water jet A so that it is injected into the raw material water A from the gas nozzle of ejector-type gas nozzle 17 as fine gas bubbles. A high concentration ozone water solution is produced by dissolving ozone into the raw material water A due to the gas-liquid reaction between the ozone fine gas bubbles and the raw material water A.
