When the water is greater than 300 m3 / h or more, square cooling tower fan control can achieve more. With the increasing number of fans can handle the amount of water increases. Windy square tower models can be as the summer outdoor wet bulb temperature changes arbitrarily increase or decrease the number of fans for DIF larger areas more conducive to energy conservation. Adjust the running time of the dance halls, bars and other entertainment operations Summer time is usually only evening show business, for about 19 to 22 o'clock. 2 ~ 4h before operating the central air conditioning system put into operation, the use of storage capacity envelope so that the temperature of the hall slowly drop to the lower limit of the design temperature or slightly below this value. So that when operating the indoor heat load gradually increase the formation of peak air-conditioning equipment still lower than at peak load in normal operation, to "pre-cool" the purpose of reducing air-conditioning equipment capacity, equivalent to approximately 25% reduction in design cooling load . Appropriately adjusting the set temperature of the chiller central air conditioner in summer electricity consumption up to 55% of total hotel electricity. Appropriately adjusting the set temperature of the chiller can receive better energy efficiency. Cold water temperature is higher, the lower the rate of the host power. Each increase of 1 ℃, saving about 3%. When the cold water setting temperature increase, subject to the load side of temperature requirements. Increase the cold water temperature set in two ways: First, the cold water temperature with the outdoor temperature settings; the second is the cold water temperature with thermal load settings. Hisense Inverter hang presses automatically shut down, turn the fan Published: January 13, 2015 Source: Unknown Hits: 141 Symptom: press automatic shutdown Xuzhou Hitachi central air conditioning sales, fans turn cause analysis: the case of such a failure first check Code lamp LED1, LED2, LED3 display state as a bright flash, off the overcurrent protection, troubleshooting, mainly divided into the following steps: (1) emphasis on the DC20V gear multimeter, measure the resistance R14 for voltage of about 1.5V (this voltage change with the current changes) If you have around 1.5V voltage Xuzhou central air conditioning prices, indicates that it is a problem, if there is no voltage of 1.5V, indicating a pre-existing problems LM358N Xuzhou central air conditioning maintenance call when measuring voltage When 5V, breakdown diode D5 described (2) measuring whether the resistance R11 of the voltage of about 0.09V (with a current variation of this voltage changes), if there is a voltage of about 0.09V, description LM358N poor, if no voltage is 0.09V described before Problems level sampling resistor (3) with a multimeter ohm power measurement sampling resistor R5, R1, R56 is open, the measured R1, R5 normal resistance, R56 R56 resistor open replace troubleshooting.
