Linkage control method for multi-energy cooling and heating

Abstract

The invention provides a linkage control method for multi-energy cooling and heating. The linkage control method comprises the following steps that by taking a whole year as a cycle, firstly whether the current energy supply season is winter or summer is judged; the winter working condition heat supply comprises the following steps that a ground source heat pump unit is automatically controlled to operate according to the water outlet temperature of a system; operation parameters of the ground source heat pump unit is read, the frequency or the number of the ground source heat pump unit is adjusted according to the operation parameters, and it is guaranteed that the ground source heat pump unit operates under the optimal working condition; the cooling method under the summer working condition comprises the following steps that a magnetic levitation unit is preferentially started under the condition that the energy efficiency of the magnetic levitation unit is higher; and under other conditions, the ground source heat pump unit and the magnetic suspension unit are operated. According to the linkage control method, through effective combination of the magnetic suspension unit and the ground source heat pump unit, the heat supply amount in winter can be guaranteed, segmented recharge control of the working condition in summer can be further achieved, and ground cold and heat unbalance is effectively prevented.

Description

technical field [0001] The invention relates to the fields of environment and energy, in particular to a linkage control method for multi-energy cooling and heating. Background technique [0002] Ground source heat pump is one of the main forms of clean energy cooling and heating. Since ground source heat pump is a heating and air conditioning system that uses shallow geothermal resources on the earth's surface (usually less than 400 meters deep) as a cold and heat source for energy conversion, Therefore, when the ground source heat pump system is cooling in summer, the excess heat in the building is exchanged to the underground rock and soil layer through the compressor; when heating in winter, the ground source heat pump is working through the compressor to extract the underground heat and send it into the room. Building heating. The energy discharged into the ground by the ground source heat pump will have a relatively large temperature impact on the rock and soil around...

Problems solved by technology

[0003] At present, when buildings use ground source heat pumps for cooling and heating, they generally use a single energy source. However, the cooling and heating requirements of northern buildings are less heat and more cold. When the cooling effect is reduced
