Xi'an Xi'an home central air-conditioning sales of central air conditioning installation, hurry up, go rush to buy, you can also call us! Central air-conditioning system is usually divided into two chilled water and cooling water systems, chilled water system is divided into cooling mode and heating mode These modes are controlled by the inverter, to explain to you the following: [1] closed loop cooling mode control system chilled water pumps in the program to ensure that the case of the terminal equipment supplied chilled water flow to determine a freeze minimum operating frequency pump inverter work, set it to lower frequency and locked, frequency chilled water pump frequency is regulated by the temperature sensor detects the temperature of the chilled water return chilled water system installed on the backwater of competence, and then through temperature control It is set to control the frequency increase or decrease the temperature of the inverter. [2] heating mode chilled water pump system, closed-loop control of the mode control scheme is in the central air conditioning heat pump operation (ie heating) when chilled water pump system. Cooling mode control scheme with the same, to ensure the flow of chilled water terminal equipment supplied, to determine the minimum operating frequency of a frozen pump drive to work, set it to lower frequency and locked, frequency chilled water pump frequency adjustment by a temperature sensor mounted on the chilled water system in charge of detecting backwater backwater chilled water temperature, and then set temperature via temperature controller to control the frequency inverter decrease.
