Evaporative chiller

Evaporative chiller, also known as evaporative cooling chiller, abbreviated as "evaporative cold water machine".

The evaporative chiller unit integrates and combines the cooling water system with the condenser of the refrigeration unit. It uses an evaporative condenser condenser, which eliminates the cooling tower, cooling water pump, cooling water pipeline, and accessories that are external to the refrigeration unit. It changes the traditional external circulation mode of cooling water to an internal circulation mode, greatly simplifying the cooling water system and reducing the loss of floating water, thereby greatly improving the energy efficiency ratio of the air conditioning system. The difference between evaporative refrigeration units and other refrigeration units (water-cooled and air-cooled) is that their condenser mainly uses the latent heat absorbed by the evaporation of cooling water to cool the refrigerant vapor. The heat released during refrigerant vapor cooling is transferred to the water film outside the pipe through the oil film, pipe wall, and dirt, and then transferred to the air through the evaporation of water.

Product features:
1System high energy efficiency ratio
Under standard operating conditions, the overall energy efficiency ratio of the machine reaches 3.5-4.5, saving more than 20% energy compared to water-cooled units and more than 35% energy compared to general air-cooled units;
2. No need to configure a cooling tower
By using flat liquid film evaporation condensation technology, the evaporation of water film on the surface of the plate is fully utilized, and the cooling and condensation of the working fluid inside the plate can be achieved through mass and heat transfer with a small air volume and a small amount of cooling water,
There is no need for cooling towers and high-power cooling water pumps, condensing fans, power distribution for water pumps, and a significant reduction in initial project investment.
3. Full heat recovery patented technology, heat recovery effectRate of over 90%
Using low-temperature and low humidity indoor exhaust as the cooling air for the evaporative condenser not only utilizes the sensible heat (temperature difference) of indoor exhaust, but also the latent heat (temperature difference) of indoor exhaust, resulting in improved condensation efficiency
The result is significantly better than directly using outdoor air as cooling air, avoiding energy loss caused by air displacement ventilation. Compared with existing air conditioning units, it has significant energy-saving effects and annual operating costs
Using it can save 30% -40%.
4. Significant water-saving effect
By utilizing advanced and reasonable water film water cooling method, the cooling water is fully wetted with the surface of the condensing plate, enhancing the heat transfer of the condensing plate and effectively overcoming the problem of flat wall water film on the plate“
The scaling phenomenon caused by dryness; In addition, the phenomenon of "flying water" in cooling towers has been completely eliminated, and compared with water-cooled units using cooling towers, a water saving rate of over 50% can be achieved.
5. No need for condensate discharge system
The condensate water to be discharged from the air conditioning system can be directly used as cooling water in the unit cooling water system without the need for an independent condensate water discharge system. Due to the low temperature of the condensate water, it can be recovered
The cooling capacity of condensed water improves the cooling effect and further reduces the consumption of cooling water.

1）The air-cooled condenser relies on 35 degree wind to remove the heat from the snow seeds, and this design can generally cool the snow seeds to 50 degrees.

2）A water-cooled condenser relies on water at 32 degrees Celsius to cool snow seeds, and can generally cool snow seeds to 42 degrees Celsius.

3）Evaporative condenser uses a 28 degree wet bulb wind to remove the evaporated water vapor sprayed on the surface of the condenser, which can generally cool the snow seed to 37 degrees.

6) The crew is equipped with R485 remote control system.
