Description
Technical field
The utility model relates to air conditioner technical field, particularly relates to a kind of independent temperature-humidity control air-conditioner water system.
Background technology
In middle-size and small-size system and villa intermediate item, independent temperature-humidity control system is widely used, and it not only brings comfortable aerobic environment, also can regulate the temperature and humidity of environment needed for house simultaneously.Independent temperature-humidity control system comprises handpiece Water Chilling Units, chilled water pump, constant pressure water compensation apparatus, water treatment facilities, end equipment.As everyone knows, at our capillary as air conditioning terminal, in order to fully improve residence comfort, being designed to " the permanent oxygen of constant temperature and humidity " ecological radiation air-conditioner refrigeration/heating system, improving comfort level with fresh air replacement acting in conjunction.On room furred ceiling (or metope, ground) install radiation capillary, the indoor sensible heat load of capillary end System Take in winter, the hot water 35/30 DEG C of logical lower temperature, mildly to room radiations heat energy; The indoor sensible heat refrigeration duty of capillary end System Take in summer, 17/20 DEG C, the cold water (minimum supply water temperature is 16 DEG C) that in radiant tube, logical temperature is higher, mildly to room radiation cold.Summer chilled water in main frame cooled dose be cooled to about 7 DEG C after be sent to plate type heat exchanger, then deliver to capillary end by plate type heat exchanger heat exchange to 17 DEG C; Winter hot water in main frame cooled dose be warming up to about 45 DEG C after be sent to plate type heat exchanger, then deliver to capillary end by plate type heat exchanger heat exchange to 35 DEG C.Hot water and chilled water share a set of pipe-line system.Fully demonstrate a kind of energy-conservation, efficiently, the theory of intelligence.
Transition season outdoor temperature is human body comfort temperature, does not need to open end capillary for a long time and regulates indoor temperature, in this case, easily cause water pump because lack of water causes some to damage.Original technology is between water knockout drum and water collector, install motor-driven pressure-difference by-passing valve additional, and controls its switch size by pressure sensor.By temperature sensor TE-1, proportional integral temperature controller TC 1 and electric control valve TV 1 forms temperature control system, be arranged on the TE 1 of water pipe, the temperature signal detected is sent to TC 1, by TC 1, the detected value of TE 1 is constantly compared with setting value, constantly output signal, the aperture of control TV 1 connects adjustable, and the environment temperature finally making TE 1 measure remains in the temperature range of setting simultaneously.Although such method possible in theory, due to the restriction of practical operation and mounting technique, our sensor can not effectively export data to electric two-way valve; Or the data fluctuations scope of input is minimum, can't reach the unlocking condition of two-way electronic valve, thus cause chilled water cannot bypass, hydraulic pressure be inadequate, and then water pump is caused burn or suppress pump accident.
Another kind method adopts variable frequency pump system exactly, but this system is when terminal temperature difference effect is very little, and what just become is unable to do what one wishes, can increase energy consumption on the contrary.And the frequency of variable frequency pump has become, the flow of water pump and lift all can have a change, cannot know and fall unnecessary chilled water with or without bypass.The frequency conversion of water pump also has lower limit, infinitely can not reduce rotating speed, and the little pump type of villa class is all very little in addition, adopts frequency converter also not gear to actual circumstances.
Utility model content
For the defect of above-mentioned prior art, the utility model provides a kind of independent temperature-humidity control air-conditioner water system, improve the safe operation operating mode of water pump, can not be not obvious and cause two-way electronic valve switch not in time and then the accident causing water pump lack of water to cause due to the fluctuation of pressure sensor.
