2. Fan coil unit - Wikipedia

   en.wikipedia.org/wiki/Fan_coil_unit

   These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.

3. Dehumidifier - Wikipedia

   en.wikipedia.org/wiki/Dehumidifier

   They work by drawing moist air over a refrigerated evaporator with a fan. There are 3 main types of evaporators. They are coiled tube, fin and tube, and microchannel technology. The cold evaporator coil of the refrigeration device condenses the water, which is removed, and then the air is reheated by the condenser coil. The now dehumidified, re ...

4. Thermal expansion valve - Wikipedia

   en.wikipedia.org/wiki/Thermal_expansion_valve

   A thermal expansion valve is a key element to a heat pump; this is the cycle that makes air conditioning, or air cooling, possible.A basic refrigeration cycle consists of four major elements: a compressor, a condenser, a metering device and an evaporator.

5. Internally grooved copper tube - Wikipedia

   en.wikipedia.org/wiki/Internally_grooved_copper_tube

   Grooved coils facilitate more efficient heat transfer than smooth coils. [1] [2] Small diameter coils have better rates of heat transfer than conventionally-sized condenser and evaporator coils with round copper tubes and aluminum or copper fin that have been the standard in the HVAC industry for many years. Small diameter coils can withstand ...

6. Evaporator - Wikipedia

   en.wikipedia.org/wiki/Evaporator

   An evaporator is a type of heat exchanger device that facilitates evaporation by utilizing conductive and convective heat transfer, which provides the necessary thermal energy for phase transition from liquid to vapour. Within evaporators, a circulating liquid is exposed to an atmospheric or reduced pressure environment causing it to boil at a ...

7. Heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Heat_exchanger

   For cooling coils, chilled water and refrigerant are most common. Chilled water is supplied from a chiller that is potentially located very far away, but refrigerant must come from a nearby condensing unit. When a refrigerant is used, the cooling coil is the evaporator, and the heating coil is the condenser in the vapor-compression ...
