Refrigerant Dehumidifier Overview

A Refrigerant or “Compressor” Dehumidifier Easy Guide

TYPICAL INDUSTRIAL STORAGE
RULE OF THUMB

Industrial buildings will be higher ceilings, larger air flow from outside so need to consider a more powerful unit for the space than for a home for instance. Also great care must be given to what is being stores in the space. Farm produce for instance will contain a lot of water compared to sealed merchandise. High roofs take off 30%. For large moisture content conditions take 50%

POOL AREA & CHANGING ROOM
RULE OF THUMB

Pool areas obvious are more humid than hanging areas. If there is a large surface area of glass to keep clear in the pool area, consideration may be needed to create a curtain of dry air down the glass with the DSR12, 20 or LD800 dehumidifiers using additional duct work

Glass will act as a dehumidifier condensing moisture in the room and special consideration may be needed.

D850 / D950 CAN BE USED AT POOL SIDE

Ideally hard wired into the mains electricity supply. Keep unit out of direct sunlight. Any shelving above the dehumidifier should be kept to a minimum depth & height above the dehumidifier. Any shelf should not hinder air flow. Avoid any alcoves. Failure to do these points will result in not only poor performance but also will shorten the lifetime of the dehumidifier.

Laws vary by country. In Europe, the minimum distance from a water source for an electrical item is 2 meters.

D850 / D950 / D1100
POSITION IN A TYPICAL TRAINING ROOM

Do not wall mount over the swimming pool. Position at least 2 meters / 6 feet away from the water’s edge. Either drain the condensate back into the pool, to a floor drain or through the wall to the outside.

If the condensate is to the outside ensure there is no prospect of the drain freezing..

Operational Parameters

1). When room humidity is reaches reset level (or < -2% RH), unit will stop dehumidifying

– COMPRESSOR OFF – POWER indicator OFF (compressor in 3 minutes protection mode)

– FAN will be OFF after 10 minutes – H/L LED indicator OFF

Within 10 minutes, if the humidity is > set level + 3%RH, COMPRESSOR will turn ON again for dehumidifying)

DEFROST SENSORS

One COPPER head sensor for internal refrigeration tube temperature) and one RESIN head sensor to sense room temperature through air drawn through the filter.

STEP A:

a). When Room Temperature (RT) ≤16℃, the Copper head sensor will not sense the tube temperature.

b). When 5℃≤ RT ≤12℃, COMPRESSOR ON 30 min./ OFF 10 min.

c). When 12℃< RT ≤16℃, COMPRESSOR ON 45 min./ OFF 10 min.

d). When RT < 5℃, Unit will not ON or STOP automatically.

STEP B:

e). When RT >16℃, and COMPRESSOR working 45 min., Copper head sensor starts to sense copper temperature.

When Copper tem. ≤ -1℃, COMPRESSOR OFF / FAN still ON=> starts Defrost 10 min.

f). After 10 min., will repeat condition “e” procedure and RECYCLED.

g). Under “e” condition but NOT in 10 min. defrost, if RESIN head sensor RT≤16℃, unit system will revert back to STEP A.
