Abstract
The utility model discloses a cooling water circulation system which comprises a refrigerating machine cooling water system, a heat recovery device, a defrosting system arranged inside a refrigerator, and a water storage pool. The water outlet end of the refrigerating machine cooling water system is communicated with one water inlet end of the heat recovery device through a pipeline. The water outlet end of the heat recovery device is communicated with the water inlet end of the defrosting system through a pipeline. A water draining system is arranged on the ground surface inside the refrigerator. The water draining system is communicated with the water storage pool through a pipeline. The water storage pool is communicated with the other water inlet end of the heat recovery device through a pipeline. Compared with an evaporator, the cooling water circulation system is high in defrosting speed and efficiency, complete dissolution of frost is ensured due to high-temperature cooling water, meanwhile, hot water is not required to be additionally prepared, the cooling water circulation system saves energy and is environmentally friendly, and the operating cost is reduced.
Description
Technical field
The utility model relates to a kind of cooling water recirculation system.
Background technology
Need low temperature below long-term maintenance-20 ℃ in freezer in the bird job shop, with 32 ℃ of the outdoor temperature difference of freezer nearly.Put into or transport the process of freezer at frozen product, freezer door is opened and is caused the outdoor heat of freezer to enter, and causes door, wall and the relevant device surface formation frost layer of freezer.Frost layer can cause refrigerating efficiency reduction, equipment corrosion.Defrost method adopts the evaporimeter of freezer to carry out defrosting usually at present, perhaps adopts the preheating water of another system to carry out defrosting.If adopt the freezer evaporimeter to carry out defrosting, the time is longer, and efficient is low; The preheating water defrosting of another system needs power consumption that water is burnt heat, waste resource and cost.
Summary of the invention
The purpose of this utility model is to provide a kind of efficient defrosting, the cooling water recirculation system of the cost that economizes on resources simultaneously.
For achieving the above object, the utility model is by the following technical solutions:
A kind of cooling water recirculation system, it comprises cryocooled water system, heat reclamation device, is arranged on defrosting system, cistern in freezer, the water side of described cryocooled water system is communicated with the water inlet end of heat reclamation device by pipeline, the water side of heat reclamation device is communicated with the water inlet end of defrosting system by pipeline, ground surface in described freezer is provided with drainage system, drainage system is communicated with cistern by pipeline, and cistern is communicated with another water inlet end of heat reclamation device by pipeline.
The water inlet end of described defrosting system and another water inlet end of heat reclamation device are respectively equipped with water pump.
Be provided with temperature sensor in described freezer, the water inlet end of defrosting system is provided with choke valve, and described temperature sensor is electrically connected to choke valve.
Described cistern is arranged on the underground.
The water side of described heat reclamation device is provided with the temperature monitoring instrument.
The utility model adopts above technical scheme, cooling water heat in refrigeration machine is reclaimed, cooling water is completed heat exchange in heat reclamation device after, temperature can reach 70-80 ℃, the defrosting system utilizes these cooling waters to carry out defrosting to freezer, cooling water after defrosting enters cistern by drainage system, the water of cistern enters again in heat-exchange device recycling, and simultaneously, the cryocooled water system constantly fills into fresh cooling water to heat-exchange device.The utility model is faster than evaporimeter defrosting speed, and efficient is high; High-temperature cooling water has guaranteed the thorough dissolving of frost.Simultaneously, do not need to prepare in addition hot water, energy-conserving and environment-protective reduce operating cost.

The water inlet end of described defrosting system 3 and another water inlet end of heat reclamation device 2 are respectively equipped with water pump 7,6.
Be provided with the temperature sensor (not shown) in described freezer, the water inlet end of defrosting system 3 is provided with the choke valve (not shown), described temperature sensor is electrically connected to choke valve, temperature in the temperature sensor senses freezer, the water velocity that enters defrosting system 3 by throttle valve control.
Described cistern 4 is arranged on the underground.
The water side of described heat reclamation device 2 is provided with temperature monitoring instrument (not shown).
The utility model operation principle: cryocooled water system 1 thermotropism conversion equipment 2 is constantly inputted cooling water, cooling water is completed heat exchange in heat reclamation device 2 after, temperature can reach 70-80 ℃, defrosting system 3 utilizes these cooling waters to carry out defrosting to freezer, cooling water after defrosting enters cistern 4 by drainage system 5, the water of cistern 4 enters again in heat-exchange device 2 recycling, simultaneously, cryocooled water system 1 automatically, constantly fill into fresh cooling water to heat-exchange device 2.
