The Surna dehumidifier uses refrigerant R410a
on the vapor compression cycle to remove
heat and moisture from the environment. Low-
pressure refrigerant gas is compressed in the
compressor and flows to the condenser coil. The
refrigerant condenses to a liquid and gives off
heat to the outside air. The refrigerant pressure
and temperature are reduced by passing through
a series of capillary tubes which act like an
expansion valve. Refrigerant then flows to the
evaporator coil. The evaporator coil is where heat
is transferred from the incoming air to the liquid
refrigerant causing it to evaporate. This is the point
in which moisture condenses out of the humid
air through condensation. Next, refrigerant flows
from the evaporator to the accumulator, entering
the accumulator as a mixture of liquid and gas.
The accumulator prevents liquid refrigerant from
entering the compressor, boiling off liquid so that
only hot, low pressure gas enters the compressor
and the cycle begins again.
