1. An indirect heat pump system, comprising:
a refrigerant unit comprising a compressor, a condenser, a throttle valve, and an evaporator, wherein an outlet of the compressor communicates with a first inlet of the condenser, a first outlet of the condenser communicates with a first inlet of the evaporator through the throttle valve, and a first outlet of the evaporator communicates with an inlet of the compressor;
a cold water handling unit, wherein a cold water inlet of the cold water handling unit communicates with a second outlet of the evaporator, a cold water outlet of the cold water handling unit communicates with a second inlet of the evaporator, the cold water handling unit is connected to a plurality of loads in parallel, and a plurality of cold water two-way valves are disposed in pipelines of the cold water handling unit and are configured to control on and off of cold water in the plurality of loads; and
a hot water handling unit, wherein a hot water inlet of the hot water handling unit communicates with a second outlet of the condenser, a hot water outlet of the hot water handling unit communicates with a second inlet of the condenser, the hot water handling unit is connected to the plurality of loads in parallel, and a plurality of hot water two-way valves are disposed in pipelines of the hot water handling unit and are configured to control on and off of hot water in the plurality of loads,
wherein the plurality of hot water two-way valves correspond to the plurality of cold water two-way valves in a one-to-one manner and are interlocked with the plurality of cold water two-way valves in terms of on and off states;
wherein the cold water handling unit comprises a plurality of inflow cold water branches communicating with the cold water inlet and a plurality of outflow cold water branches communicating with the cold water outlet, and the plurality of inflow cold water branches and the plurality of outflow cold water branches communicate with the plurality of loads and are configured to introduce the cold water to the plurality of loads;
wherein the plurality of inflow cold water branches comprise a first cold water branch, a second cold water branch, a third cold water branch, a fourth cold water branch, and a fifth cold water branch; two ends of the first cold water branch communicate with the cold water inlet and an inlet of a first load respectively; one end of the second cold water branch communicates with the first cold water branch, and another end of the second cold water branch communicates with an outlet of the first load and an inlet of a second load; two ends of the third cold water branch communicate with the cold water inlet and an inlet of a third load respectively; two ends of the fourth cold water branch communicate with the cold water inlet and an inlet of a fourth load respectively; and two ends of the fifth cold water branch communicate with the cold water inlet and an inlet of a fifth load respectively; and
the plurality of outflow cold water branches comprise a sixth cold water branch, a seventh cold water branch, an eighth cold water branch, and a ninth cold water branch; two ends of the sixth cold water branch communicate with the cold water outlet and an outlet of the second load respectively; two ends of the seventh cold water branch communicate with the cold water outlet and an outlet of the fifth load respectively; two ends of the eighth cold water branch communicate with the cold water outlet and an outlet of the fourth load respectively; and two ends of the ninth cold water branch communicate with the cold water outlet and an outlet of the third load respectively.
