    • FAQ

      Direct Expansion Evaporator System Unit Frequently Asked Questions

      This FAQ is for Direct Expansion System. More details? Pls Go Here!

      1. What is direct expansion system?

      Direct Expansion means that the refrigerant expands to produce the cooling effect in a coil that is in direct contact with the conditioned air that will be delivered to the space.

      2. What is Direct Expansion Evaporatorin mechanical engineering?

      A direct expansion refrigeration unit, also known as a condensing unit, uses condensed refrigerant liquid to cool the air in a given space. It is widely used in micro refrigeration, small refrigerators, mobile freezers, medical, laser, precision instruments, laboratory equipment, etc.

      3. What is expansion system?

      A direct expansion system enables the most compactly designed refrigerant system. A direct expansion system eliminates the use of a secondary coolant loop and uses the refrigerant to directly cool the desired payload via a cold plate. In a DX system, the evaporator absorbs heat directly from the payload.

      4. How does a direct expansion system work?

      The expansion parts (valve or capillary) controls the flow of refrigerant into the evaporator coil. Hot air is extracted from the specific space and blown over the heat exchange coil by the evaporator/indoor fan. The refrigerant in the coil absorbs the heat and expands. This lowers the temperature of the air being blown into the space/room.

      5. What is the difference between indirect and direct cooling system?

      In cooling systems, the distribution can be either direct or indirect. If direct, the cooling water goes directly into the internal piping system of a building. In an indirect system, a heat exchanger separates the internal from the external system.

      6. What is the difference between DX system and chilled water system?

      The immediate and most noteworthy difference between these two units is that the DX (direct expansion) unit cools air, and the chiller units cool water. Chiller units cool water for use in other liquid systems like chilled water handlers.

      7. What is the main function of an expansion valve or capillary?

      The expansion valve removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator. The high-pressure liquid refrigerant entering the expansion valve is quite warm.

      8. How many types of RIGID HVAC refrigeration systems?

      There are 4 types of refrigeration systems:


      1. Micro DC Aircon (Air Cooling)
      2. Plate Liquid Chiller (Liquid Cooling)
      3. Coaxial Liquid Chiller (Liquid Cooling)
      4. Coil Liquid Chiller (Liquid Cooling)
      5. Direct Expansion System (DC Condensing Unit)
