Problems solved by technology

[0004] However, many units are selected according to the maximum cooling load of the building. During most of the operation, the actual cooling load of the user is not too large, or for some water systems with small system capacity, if the maximum output load is set too high If the temperature is too high, the chilled water outlet temperature of the unit will quickly reach the set value, and the unit will easily enter the standby condition, which will cause the unit to turn on and off frequently and affect the service life of the unit
At the same time, because the temperature of the chilled water changes too fast, the user comfort is not strong
If the maximum output load is set too small and the load on the user side increases, it will take a relatively long period of time for the unit to run to reduce the temperature of the cold water to the set value, and the comfort of the user is also poor
[0005] For the above problems, no effective solutions have been proposed so far

Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0049] Considering that the maximum output load of the existing units is set before leaving the factory, professionals are required to set it up during operation. If the maximum output load is set too low or too high, it will affect the comfort of users.

[0050] In this example, a method for controlling the maximum output load of the unit is provided, such as figure 1 As shown, the following steps may be included:

[0051] Step 101: Obtain the actual load demand on the unit;

[0052] Step 102: Control the maximum load value of the unit according to the actual load demand.

[0053] In the ab...

Abstract

The invention provides a method and device for controlling the maximum output load of a unit. The method comprises the steps that the actual load demand for the unit is obtained; and the maximum loadvalue of the unit is controlled according to the actual load demand. Through the method and device for controlling the maximum output load of the unit, the existing problem of low user comfort degreein the prior art is solved, and the technical effect of effectively increasing the using comfort degree is achieved.

Description

technical field [0001] The invention relates to the technical field of equipment control, in particular to a method and device for controlling the maximum output load of a unit. Background technique [0002] In the existing chillers, the maximum output load (that is, the maximum output capacity) of many manufacturers’ units is a settable value. When the unit leaves the factory, this value will be set to a default value. Through the setting of the maximum output load The value controls the maximum cooling capacity of the unit. The maximum output load value of the unit is often set manually by personnel and cannot be adjusted automatically. [0003] During the operation of the unit, the chiller often decides whether to start or stop the unit / compressor according to whether the chilled water output reaches the set value. [0004] However, many units are selected according to the maximum cooling load of the building. During most of the operation, the actual cooling load of the...
