Control Mode Study Of Variable Primary Flow In Ground Source Heat Pump

The text analyzes the possibility of Variable Primary Flow system ,the air conditioning units and the ending of plants all can run in variable-flow system. Meanwhile introducing the constitution of variable flow system, the importance of design and the application field.Aiming at two typical control methods, the differential pressure and themoelctric temperature control ,analyzes theoretically the air condition -ing power-using characteristic in two kinds of methods,and introcuces the plants of DDC and variable-flow.In a Ground Source Heat Pump Engineering,we hold an experiment of variable-primary flow ,use the themolectric control .The text introduces the constitution of ground source heat pump in detail,the concrete steps of the themoelectric control runing, and carries on analysis to the experiment data.From the data we get the runing characteristic of ground source heat pump in themoelecric control methods.
