Definitions

  • the present invention relates to air-conditioning cooling apparatus and more particularly pertains to a water cooling system with full heat recovery.
  • Air-cooled cooling systems utilize outdoor air directly as the cooling agent to cool the apparatus. Since the refrigeration operation of air-conditioners is mainly in the seasons of higher temperature, the refrigeration efficiency of directly using outdoor air for cooling is therefore relatively low, where the COP (coefficient of performance) is maintained at around 2.0. It can be seen that this type of cooling systems is of high energy consumption. However, air-cooled cooling systems dominate the market because of the convenience in installation and the flexibility in location. Water-cooled cooling systems utilize water as the cooling agent and bring the exhaust heat of the refrigeration system to the cooling tower. Heat is then discharged outdoor by the cooling tower.
  • cooling tower can lower the temperature of cooling water to approximately the outdoor wet-bulb temperature, in comparison with the refrigeration system it has good condensation effects.
  • the refrigeration efficiency of the cooling systems is thereby increased and the COP can reach 3.8 to 4.0.
  • water-cooled cooling systems are installed with an additional cooling system, costs of the apparatus are increased and locations for installation are also limited.
  • traditional cooling towers usually use water sprinklers to spray water evenly. Water drops from this type of sprayers are relatively small. Further, there are relatively strong winds in the cooling tower. Therefore, it is common for water drops to "fly" out of the cooling tower during its operation as small water drops are carried by strong winds to spill out from the tower directly.
  • This water spillage amounts to over 50% of the total water consumption of the cooling tower, while the water used for actual evaporation and heat radiation is less than 50%.
  • the existing cooling systems produce large volume of condensate during the refrigeration process.
  • Known skills are to directly discharge the condensate that is produced. Since the temperature of condensate is as low as 10°C to 15°C, the cooling energy loss is relatively high. If the condensate can be directly recycled to assist cooling, the temperature of cooling water can be lowered and energy can be saved, and this can greatly reduce the consumption of cooling water.
  • the object of the present invention is to provide a water cooling system with full heat recovery which is highly effective, energy saving, water saving and healthy.
  • the present invention generally comprises a condenser, an evaporator, a compressor and an expansion valve; the evaporator connects with a cooling water recycling circuit; one side of the condenser is disposed in a position corresponding to a cooling air opening; the cooling air opening connects with an air pipe; the air pipe connects with an indoor air outlet and an outdoor air inlet through subsidiary pipes; the outdoor air inlet is installed with an airflow regulation valve to regulate the mixing ratio of outdoor air and indoor air, and the range of regulation ratio is 0% to 100% (i.e. the mixing ratio of outdoor air to indoor air is 0:1 to 1:1); the other side of the condenser is provided with an exhaust vent; and a cooling fan is disposed between the exhaust vent and the cooling air opening.
  • the condenser is an evaporative condenser comprising a water sprayer, a heat exchange plate or heat exchange tube, a water tank and a recycling water pump; the water sprayer is disposed above the heat exchange plate or heat exchange tube; the water tank is disposed below the heat exchange plate or heat exchange tube; the recycling water pump connects with the water sprayer and the water tank.
  • a filling can be disposed between the heat exchange plate and the water tank, for example a PVC filling.
  • the provision of a filling ensures that cooling water flowing through can be maintained at a certain temperature for a longer time.
  • the heat exchange plate comprises a plate body and the plate body is provided with channels.
  • the plate body can be provided with a flat surface on one side and with ridges protruding on the other side forming empty channels, or it can also be provided with ridges on both sides to form the empty channels.
  • the outer surface of the plate body can be a slick surface. It can also be a fortified heat conducting surface with enhanced heat exchange effects. For example, it can be provided with one or a plurality of outer wing panel.
  • the shape of the channels can be of a continuous "S" shape.
  • the cross sectional shape of the channels can be circular, elliptical, olive-shaped, square-shaped, trapezoidal or other irregular shapes; the actual shape depends on the specific production needs of the heat exchange apparatus.
  • the entrance and exit of the channels can be flexibly disposed depending on the actual usage requirement. For example, it can be disposed in a corner position of the plate body or on the sides of the plate body.
  • connection between the entrance or exit of the channels and an exterior junction can be performed by welding or flanged connection.
  • heat exchange plates There can be one or more heat exchange plates. The actual number can be flexibly adjusted depending on the refrigeration volume required. When more than one heat exchange plates are used, the heat exchange plates are arranged in parallel.
  • the water sprayer can be a slot-type water sprayer or a perforated water sprayer.
  • Slot-typed water spray troughs are disposed at the bottom of the slot-type water sprayer.
  • the exit at the bottom end of the slot-typed water spray troughs can be provided with one or a plurality of guiding plate.
  • water spray holes are disposed at the bottom of the perforated water sprayer. Guiding nozzles are disposed inside the water spray holes. The guiding nozzles are disposed in a position corresponding to the tube body which is connected with the upper end of the heat exchange plate. Owing to the guiding nozzles, water flows to the top of the tube body and along the surface of the tube body evenly to the surface of the heat exchange plate.
  • the cross section of the tube can be circular, elliptical, droplet-shaped, rhombus-shaped, square-shaped or of other shapes.
  • the present water cooling system with full heat recovery can be connected with a condensate recycle system and the condensate recycle system connects with the water sprayer or the water tank of the evaporative condenser.
  • the condensate recycle system can recycle cooling energy of the condensate to assist the cooling of the evaporative condenser.
  • the condensate recycle system comprises a water receptacle and a condensate pipe; the water receptacle is disposed below an indoor surface cooling fan; one end of the condensate pipe connects with the water receptacle and the other end thereof connects with the water sprayer or the water tank.
  • the condensate recycle system can be provided with a water pump on the condensate pipe depending on the actual needs. It provides power to transfer the condensate to the water sprayer or the water tank.
  • a filter can be disposed at the exit of the condensate pipe.
  • the evaporator can be a plate-type evaporator, a tube evaporator or a wrap-round evaporator.
  • the water cooling system with full heat recovery operates as follows: the condenser, expansion valve, evaporator and compressor of the present water cooling system with full heat recovery are sequentially connected to form a closed refrigeration circuit.
  • the refrigeration circuit utilizes a coolant (e.g. chlorofluorocarbon) for refrigeration. Since the evaporator and the cooling water recycling circuit are connected, the coolant of the refrigeration circuit and the cooling water of the cooling water recycling circuit perform cooling energy exchange inside the evaporator, thereby lowering the temperature of the cooling water. The cooling water is then used for cooling indoor air.
  • a coolant e.g. chlorofluorocarbon
  • the cooling fan introduces indoor exhaust air (of lower temperature and relative humidity) and outdoor air from the indoor air outlet and the outdoor air inlet into the space in which the evaporative condenser is located in order to perform heat exchange with the evaporative condenser and with the cooling water that flows through the evaporative condenser.
  • the cooling water transfers heat to the cooling air by transferring heat (sensible heat) to the cooling air and by evaporating water (latent heat) of the cooling air.
  • the temperature of the cooling water decreases and the temperature of the cooling air (indoor exhaust air and outdoor air) increases. Finally, it is discharged from the machine from the exhaust vent through the cooling fan.
  • the condensate recycle system can at the same time recycle the condensate of lower temperature and mix it with the condensate in the evaporative condenser, thereby reducing the overall temperature of the condensate. This serves to assist the cooling of the evaporative condenser and effectively uses the cooling energy and saves water.
  • the present invention utilizes low temperature, low humidity indoor exhaust air as cooling air for the evaporative condenser. It makes use of the sensible heat (temperature difference) of indoor exhaust air as well as the latent heat (humidity difference) of indoor exhaust air.
  • the condensation effect is much better than directly utilizing outdoor air as cooling air. It prevents energy loss due to air exchange and ventilation and attains prominent energy saving effects when compared with the existing cooling systems. Annual operational costs can be reduced by more than 30%.
  • the present invention does not require a condensate discharge system.
  • the present invention directly recycles condensate which is discharged in the existing facilities into the cooling water system as cooling water. Since the temperature of the condensate is low, the cooling energy of the condensate is recycled and better cooling effects can be attained. Direct recycle of the condensate also prominently saves cooling water consumption of the cooling systems. When compared with cooling systems using cooling towers, the present invention has a very high water-saving efficiency.
  • the present invention does not require a cooling tower or a powerful cooling water pump, thereby lowering engineering costs and energy consumption.
  • the present invention can save more than 15% of energy in this regard. Since no cooling tower is required, the water-film spraying of the condenser of the present invention completely eliminates water spillage. Therefore, when compared with other cooling systems using cooling towers, the present invention can attain water saving effects of over 50%.
  • the present invention recycles energy to the largest extent and lowers energy and water consumption. It effectively solves the problems of increased energy consumption due to an increase in fresh air volume of air-conditioning systems. It possesses the features of energy and water saving and healthy application. It can be widely used in the air-conditioning systems in restaurants, hospitals, supermarkets, villas, offices and so forth. It has wide applications and good market prospects.
