ABSTRACT:
A low temperature dehumidifier wherein a high pressure fan removes air from an enclosed skating rink. The fan discharges the air into and through an air-conditioning unit. The use of the fan results in a positive pressure in the air-conditioner upstream of the cooling coil. The pressure increases the temperature of the air; moisture is removed when the air contacts the cooling coil, but ice formation on the coil is prevented. The air is discharged on the downstream side of the coil and experiences a pressure drop, further cooling the air which is returned to the skating rink.
