The invention discloses a ground source
heat pump air-conditioning
system device based on peak regulation and
energy storage as well as a control and operation method thereof. Particularly, the
system is divided into two parts including a connection structure of
system parts and an operation and control model. An inlet pipeline and an outlet pipeline of an
energy storage box are respectively connected with temperature sensors, a
solenoid valve,
convertible frequency water pumps,
electromagnetic flow meters, a water collector and the like. Two groups of
water source heat pump units are connected between the inlet pipeline and the outlet pipeline of the
energy storage box in parallel; three groups of the
convertible frequency water pumps are connected between the outlet pipeline and a water
distributor in parallel; and
pressure difference transmitters are connected with the input ends and the output ends of N groups of fan coils in parallel.
Signal harnesses of a programmable controller are respectively connected with the
convertible frequency water pumps, the
water source heat pump units, two
electromagnetic flow meters, three temperature sensors and three
pressure difference transmitters. The control and
operation model comprises three parts of assuring starting time and stopping time of energy storage of the system, assuring the starting time and the stopping time of regulating the peak and releasing the energy by an energy storage device, and controlling the energy storage and the energy releasing in a
transition season. According to the invention, the system is configured with a set of intelligently-controlled operation scheme, so that the load rate at a peak time interval can be greatly reduced and the operation cost is reduced by about 12%.
