Embodiment Construction
[0032] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0033] In order to ensure the stable and normal operation of the ice-source heat pump energy supply system, and to make reasonable use of the phase change latent heat, reduce the required supply of low-temperature heat sources, and improve the energy efficiency of the unit, it is necessary to control the ice content in the process of releasing latent heat from ice making. In order to obtain more heat,...

The invention belongs to the technical field of new energy resources, and particularly relates to an ice source heat pump system controllable in ice content. The ice source heat pump system comprisesan ice-water mixture preparation circulating module which is composed of a supercooled water heat exchanger, an ultrasonic supercooling relieving device and an ice-water mixture separation device. When the system operates, the ice content of a generated ice-water mixture is controlled by controlling working parameters of the ultrasonic supercooling relieving device, and controllable icing is achieved. According to the ice source heat pump system, limitation of a traditional water source heat pump to the fed water temperature is broken, the problem that in a traditional unit, an evaporator is iced and cannot work due to the fed water temperature is too low is solved, in addition, the ice content of the system can be controlled, it can be ensured that the system utilizes latent heat of phasechange to the greatest extent, and the situation that a pipeline is frozen and blocked due to the fact that the ice content is too high in the ice slurry conveying process is prevented.
Description
Technical field [0001] The invention belongs to the technical field of new energy, and more specifically relates to an ice source heat pump system with a controllable ice content. Background technique [0002] In recent years, my country has actively developed water source heat pump technology, and built a large number of water source heat pumps that use surface water such as river water, lake water, and groundwater, which have achieved good energy-saving and emission reduction effects. However, limited by groundwater, there are obstacles to the promotion of water source heat pumps. In addition, the water source heat pump has requirements for the inlet water temperature. For surface water below 4°C, the evaporator may freeze and automatically shut down during use. In winter, rivers in northern my country are frozen, and rivers with small flow in the south and lakes with small areas have lower temperatures and are not suitable for low-temperature heat sources. [0003] An ice-sourc...
