Multi-energy complementary park cold and heat combined supply device and control system thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of energy supply, and in particular relates to a multi-energy complementary park cooling and heating combined supply device and a control system thereof. Background technique [0002] Energy is an important pillar of social and economic development and progress. While the demand for energy is increasing, the problems of environmental pollution and imbalance between energy supply and demand are intensifying. At present, the state of energy management in the park is mainly reflected in the fact that traditional energy is dominant, clean energy accounts for a relatively low proportion, and energy consumption is large and environmental pressure is high. The strategy to solve this situation is to optimize the energy structure, increase the proportion of clean energy, and at the same time realize comprehensive energy supervision and efficient and accurate real-time energy regulation. Therefore, the application of...
