The LAO will protect the compressor and refrigerant system. It has two distinct components;
a crankcase heater to keep the oil in the compressor warm and prevent slugging on start-up,
and a head pressure control to automatically cycle the condenser fan on and off to maintain
system head pressure.
To confirm that the system is working, feel the bottom of the heater when the compressor
unit has cycled off. When the unit starts, the condenser fan does not start at the same time as
the compressor. The condenser fan starts after the head pressure has built up. As the unit is
running, the condenser fan cycles off and on while it holds the head pressure within a fixed
range. The colder the air, the more frequent the cycling and the longer the duration.
Humidifier and Humidistat
A popular option for the CellarMate is the humidifier, supplied with a sheet metal adapter
box and a pre-wired humidistat. The humidifier is designed for field installation and can be
retrofitted onto existing CellarMate units. Each humidifier model is furnished with an
electronic digital humidistat to control the humidity in the cellar. The humidifier mounts
onto the CellarMate unit using the common drain, and requires a hot water supply. No
additional external power is required.
When the humidistat calls for humidity, a damper inside the enclosure opens and allows air
from the evaporator fan to flow through the drip pad and back into the inlet of the unit. A
solenoid valve also opens, allowing water to flow into the distribution channel and drip down
over the pad. The air flowing over the wet pad surface adds moisture to the air and increases
the humidity in the cellar.
Since the cellar air temperature is cold, the water entering the humidifier must be HOT to be
absorbed into the air stream. To avoid the buildup of dirt on the pad, install a 5 or 10 micron
inline water filter ahead of the humidifier to keep dirt from fouling the evaporation pad
inside. To avoid the buildup of mineral deposits on the pad, install a water softener.
To insure adequate wetted surfaces and help flush away excess minerals, set the water flow
to always have a flow of water to the drain. When operating, the humidifier uses
approximately 1 to 2 gallons of water per hour. About 60% of the water passes through and
goes out the drain. There is an orifice in the line to restrict the flow of water, but a throttling
valve may be needed to keep too much water from going to the pad. All that is needed is a
steady drip of water out of the drain to ensure adequate wetting and flushing of the pad
media. Pipe a gravity drain line to an open floor or sink drain, or use a condensate pump
where a gravity drain is impractical. Discharge the excess drain water directly onto the
ground, or combine the discharge into the condensate drain from the unit, but only
downstream from the loop trap.
The CellarMate humidifier uses a 10” wide x 11” high x 2”thick pad. The rated output
capacity for wine cellars at 55°F is 1.62.3 gallons per day (gpd) with 760°F water supply,
34.57 gpd with 950°F water, and 7.45.1 gpd with 120°F water. Weight of operating
humidifier is 10 lbs.
