The invention relates to an integrated cold station system and its control method and device. The integrated cold station system includes: a container, a controller, a refrigeration unit, a heating unit, a temperature detection component, a first valve, a chilled water pipeline, a cooling water pipeline and Hot water pipes; heating units include: heat pump units, water tanks and hot water pumps; the controller determines the waiting mode according to the current water tank temperature, current frozen water supply temperature and current frozen return water temperature detected by the temperature detection component in real time. When it is a dual-machine mode, the controller controls the synchronous operation of the heat pump unit and the refrigeration unit, controls the opening of the hot water pump, and adjusts the first valve to the maximum opening, so that the heat pump unit can exchange heat between hot water and cooling water and absorb the heat of cooling water , dissipate heat to hot water. By adopting the technical scheme of the invention, the heat pump unit directly uses the heat of the cooling water to dissipate heat to the hot water, thereby reducing energy waste and energy consumption of the integrated cooling station.
Description
technical field [0001] The invention relates to the technical field of integrated cold station control, in particular to an integrated cold station system and its control method and device. Background technique [0002] At present, the integrated cooling stations used in service industries such as hotels, supermarkets and other places, because the user needs to use cold water and hot water at the same time, use container solutions to integrate chillers, water pumps and cooling towers; most heat pump units use units, water pumps and fans In one, it is supplied to the user side through the cooling (heating) of the unit. [0003] The chiller unit and hot water unit in the existing integrated cooling station will exchange heat with the air during the working process, but the energy after the heat exchange with the air can only be discharged to the external environment, resulting in energy waste and improving the integrated cooling system. Station energy consumption. For exampl...
