Embodiment Construction
[0044] The following examples can make those skilled in the technical field understand the present invention more comprehensively, but do not limit the present invention in any way.
[0045] An embodiment of the present invention provides a method for maximizing the cooling efficiency of a central air-conditioning cooling water system, including the following steps:
[0046] Step A: Optimum condensing temperature algorithm: Under different central air-conditioning system loads and outdoor wet bulb temperatures, different condensing temperatures correspond to different cooling water system power values; therefore, there is an optimal condensing temperature, so that the operating power of the cooling water system To reach the minimum, use the following formula to calculate the cooling water system power:
[0047] N=f(t c , Q, t s ),
[0048] In the formula, N is the power of the operating refrigeration unit N 1 , Cooling water pump power N 2 , Cooling tower fan power N 3 a...
