What are the main advantages of the direct expansion air conditioning unit?

This usually means the fluid must travel a very long distance to reach the internal unit inside the house for air conditioning, thus resulting in various drawbacks. This type of system is suitable for regulating the air in houses of moderate size with a small quantity.
Supplying air conditioning to numerous large venues, such as yachts, the ideal choice is a hydraulic air conditioning or "chilled water" system. The core of these circuits is the chilled water unit or "water cooler," which is connected to a series of peripheral components known as fan coils, installed in various environments for air conditioning. The entire refrigeration process occurs within the chilled water unit, where the cooling fluid is stored and heat is transferred to water. Water, a substance circulating in the piping system, passes through the vessel structure, cooling in summer and heating in winter. The main advantages of the hydraulic air conditioning system over the "direct expansion" system are as follows:
The refrigerant fluid's path is shorter, thereby reducing the workload on the compressor.
2. Due to the fluid only covering the short and compact loop inside the cooler, refrigerant fluid leaks are rarer and easier to detect.
In the event of a fire, the building must not release toxic substances.
4. Due to the thermal inertia of water, it offers more stable and accurate temperature control.
When the air conditioner is running, it performs two tasks. It can lower the space temperature and also remove moisture from the air. To complete both tasks, it must run long enough for the water to condense from the air flow. Large air conditioners often do not run long enough to fully dehumidify, as they cool the space and then shut off. As the space temperature rises again, the unit will start running, but it will shut off quickly once it reaches the set temperature point.
