The invention relates to a multi-energy complementary park cold and heat combined supply device and a
control system thereof, belongs to the technical field of
energy supply, and solves the technical problems that an industrial park only uses an air source
heat pump, cold and heat combined supply
power consumption is high, the park
voltage is low due to high-
power equipment, even the service life of various devices in the park is affected, and the heating requirement cannot be met sometimes by only using the solar heating technology. According to the solution, the multi-energy complementary park cold and heat combined supply device comprises a
solar heat collection system, an air source
heat pump unit, a
water source heat pump unit, a heat collection water tank and a constant-temperature water tank, seven loops are formed by connecting the
solar heat collection system, the air source heat pump unit, the
water source heat pump unit, the heat collection water tank and the constant-temperature water tank with park cold and heat user terminals, and the seven loops form four
modes of heating in winter and two
modes of cooling in summer.
Solar energy, air energy and other green energy sources are used for supplying (heat and cold) energy sources to the park, meanwhile, the
control system is used for controlling the multi-energy complementary park cold and heat combined supply device, finally, safe, clean, efficient and low-
carbon utilization of the energy sources is achieved, and the
energy source quality is comprehensively improved.
