What's the difference between water cooler and central air conditioner?
Warm air conditioning usually operate in the local load, and load changes, so the local NPLV or full load efficiency is important, and some industrial air conditioner operates at a fixed load, it is because of this reason Trane unit developed the BASE LOADING function.
There is also a request of less than 0 degrees, which will be the use of ethylene glycol or salt water. For ethylene glycol, the usual units can also be satisfied, but for brine, the evaporator heat exchanger tubes are best made of corrosion-resistant tubes.
Requests for industrial sites are multifarious, some request water at 15 degrees or above, some require large temperature difference, and some require low water temperature.
Usually warm air conditioning, cold water outlet temperature of 7 degrees, 5 degrees of temperature difference, at present some companies implement a large temperature difference, but at the outlet temperature of about 5 degrees, the temperature difference of 9 degrees
In fact, from the manufacturers of water chillers, the difference is not very large, but if it is from the application site, there are some differences.
