Benefits of technology

This new technology allows for better cooling by controlling how much liquid flows through it without requiring expensive machinery or complicated pipes that require regular maintenance.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency of heat exchange systems used during evaporation or condensation processes. Specifically, current methods require that each unit's own dedicated power supply needs to operate at its maximum capacity regardless whether other units are working properly with them. Additionally, these conventional methodologies have limitations such as requiring regular maintenance due to changes caused by factors like temperature fluctuations over time.

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] The primary pump variable flow system is composed of the cold source side and the load side connected through the pipe network. The cold source side includes the cold source and multiple circulating pumps 1, and the load side includes the connected water separator 2 and valves in sequence according to the water flow direction. a5, air conditioner terminal 7, electric two-way valve 8, valve b6 and water collector 3. The method of the present invention is characterized in that the evaporative chiller 11 is used as the cold source of the primary pump variable flow system, and the pressure difference controller 4 is connected in series between the water separator 2 and the water collector 3, so that the pressure difference controller 4 is respectively It is connected with the fan 10 of the evaporative chiller and the circulation pump 1 sig...

Abstract

The invention discloses a method for realizing the continuous regulation of a primary pump variable flow system by using an evaporative water cooling machine set, the evaporative water cooling machine set is adopted as a cold source at the cold source side of the primary pump variable flow system, and a pressure difference controller is connected in series between a water separator and a water collector at a load side, so that the pressure difference controller is respectively connected with a fan and a circulating pump of the evaporative water cooling machine set through signals and the circulating pump and the fan are continuously regulated under the action of the pressure difference controller. in addition, not only operation platform number control can be carried out on the circulating pump is not only subjected to operation platform number control, but also to variable frequency modulation, and the air volume of the exhaust fan of the evaporative water cooling machine set is correspondingly regulated along with the change of the load side, thereby saving transportation energy consumption.
