Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.
As depicted in figs. 1 and 2, a kind of HVAC steady pressure of system exhaust apparatus, including vacuum tank 1, air bleeding valve 2, breather valve 3, pressure transducer 4, water-level instrumentation 5, control unit 6, brine tank 7, preservative case 8, water quality testing meter 9, air bleeding valve 2 is arranged on the top of vacuum tank 1, breather valve 3 connects vacuum tank 1 and outside atmosphere, water-level instrumentation 5 is in being arranged on vacuum tank 1 on the sidewall of close bottom surface, and air bleeding valve 2, breather valve 3, pressure transducer 4, water-level instrumentation 5 are connected with control unit 6 respectively.
Vacuum tank 1 is connected in the circulation waterway 12 of HVAC system by water inlet pipe 10 and outlet pipe 11 respectively, and water inlet pipe 10 is provided with water compensating valve 13, and outlet pipe 11 is provided with drain valve 14, water compensating valve 13 and drain valve 14 and is connected with control unit 6 respectively.When the water level in water-level instrumentation 5 monitors vacuum tank 1 is too low, control unit 6 controls water compensating valve 13 moisturizing in tank, and breather valve 3 opens outside aerofluxus simultaneously, thus ensures that the dischargeable capacity of vacuum tank 1 is 100%.
Pressure transducer 4 is connected with outlet pipe 8, when pressure transducer 4 detect discharge pressure too high time, control unit 6 controls air bleeding valve 2 and outwards bleeds, simultaneously closes off breather valve 3, to reduce pressure inside the tank；When discharge pressure is too low, by water compensating valve 13 moisturizing in tank, simultaneously close off breather valve 3, to increase pressure inside the tank.
According to Henry's law, gas is dissolubility and water temperature and pressure correlation in water, at a certain temperature, is directly proportional to the pressure of gas.When air bleeding valve 2 is outwards bled, in tank, the pressure of the water surface reduces, and makes gas evolution soluble in water, makes stable water pressure, decrease cavitation and the noise pollution of water pump, improves heat exchange efficiency and the dehumidification function of end-equipment.
