Abstract

PURPOSE: A drain apparatus with a siphon tube and a drain control technique are provided to prevent drained water in a siphon tube of a heat exchanger from flowing back into the heat exchanger. CONSTITUTION: A water supply electronic valve(15) is closed and an air vent electronic valve(18) is opened to keep an inside of a heat exchanger(1) at atmosphere pressure. A drain electronic valve(13) is opened to allow water to be drained through a siphon tube(17) installed on an outlet side header(7). A float switch(6) senses water drained into a drain plate(3) to operate a drain pump(5). Water in the siphon tube is drained through a drain auxiliary chamber(12) by negative pressure generated in the drain auxiliary chamber so that water in the heat exchanger is completely drained. The float switch is turned off to stop the drain pump and close the drain electronic valve and the air vent electronic valve when drainage of the heat exchanger is completed. An apparatus works to prevent damage of the heat exchanger due to freezing when indoor temperature drops down to sub-zero temperature while the heat exchanger is not working.

During cooling and heating operation, the solenoid valve 15 is opened and cold or hot water is supplied to the heat exchanger. The indoor air is discharged to the manual air vent (4) and the indoor air is heat exchanged with the heat exchanger (1). When indoor air conditioning stops for a long time, the cold or hot water is drained in the heat exchanger (1). According to Fig. 2, the drain proceeds toward the supply pipe 8, and the supply pipe 8 is installed by the drain plate 3 structure and the casing finish at positions 3 to 4 at the lower end of the inlet side hedda. (1) Drain from the upper end to the supply line (8), and the lower end is frozen. The remaining water freezes when the room temperature drops below zero to break the heat exchanger (1). In order to prevent this, according to FIG. 5, the water solenoid valve 15 is closed, the air band solenoid valve 18 is opened to maintain the atmospheric pressure in the heat exchanger 1, and the drain solenoid valve 13 is opened. Drain proceeds through the siphon tube 17 provided in (7). The water drained to the drain plate 3 is sensed by the float switch 6, and the drain pump 5 is operated. A negative pressure is generated in the 12) so that the water in the siphon tube 17 is drained through the drain auxiliary chamber 12, so that no water is accumulated in the heat exchanger 1. The drain pump 5 stops when the float switch 6 is turned off, and the drain pump 5 is stopped and the drain solenoid valve 13 and the air band solenoid valve 18 are closed. Is complete.
