Abstract
Abstract Apparatus in an air conditioning unit to provide for circulation of evaporator condensate preventing the formation of pockets of cold condensate which cause exterior condensation on the unit, the apparatus comprising a reservoir area for the collection of condensate, a condenser fan shroud dividing the reservoir into two parts and sluiceways within the shroud defining a path for circulation of the condensate communicating with the reservoir, and a powered rotatable fan which creates air pressure differentials which cause the condensate in the reservoir to circulate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
An air conditioning unit which prevents exterior condensation from forming on the unit being divided by a partition into an evaporator section containing an evaporator on which condensation is formed and a condenser section containing a condenser and a rotatable condenser fan and the unit having a motor to rotate the fan, comprising: a base pan which defines a reservoir in the condenser section of the unit; fluid transfer means from the evaporator section to the reservoir; and a condenser fan shroud which divides the reservoir into two parts and which has sluiceways communicating with the reservoir located in the condenser fan shroud, whereby air pressure differentials resulting from fan rotation cause the condensation in the reservoir to circulate through the sluiceways eliminating pockets of cold condensation.
Claim 2
Dependent Claim
127 words
An air conditioning unit which prevents exterior condensation from forming on the unit being divided by a partition into an evaporator section containing an evaporator on which condensation is formed and a condenser section containing a condenser and a rotatable condenser fan and the unit having a motor to rotate the fan, comprising: a base pan which defines a reservoir in the condenser section of the unit; fluid transfer means from the evaporator section to the reservoir; and a condenser fan shroud which divides the reservoir into two parts and which has sluiceways communicating with the reservoir located in the condenser fan shroud, whereby air pressure differentials resulting from fan rotation cause the condensation in the reservoir to circulate through the sluiceways eliminating pockets of cold condensation.
Claim 3
Dependent Claim
57 words
Apparatus as set forth in claim 1 where the fluid transfer means consists of a drain pan mounted to collect condensation drippings from the evaporator, an opening in the partition communicating with the reservoir, and a drain pan outlet communicating with the drain pan on one end and the opening in the partition with the other end.
Claim 4
Dependent Claim
27 words
Apparatus as set forth in claim 1 wherein there are two sluiceways in the condenser fan shroud one being located on each side of the condenser fan.
Claim 5
Independent Claim
131 words
The method of preventing exterior condensation in an air conditioning unit, said unit being divided by a partition into an evaporator section containing an evaporator on which condensation is formed and a condenser containing a condenser and a rotatable condenser fan, and the unit having a motor to rotate the fan, which comprises: locating a reservoir in the condenser section of the unit; transferring condensate from the evaporator to the reservoir; dividing the reservoir into two parts with a condenser fan shroud containing an opening for the condenser fan; and providing sluiceways in the condenser fan shroud communicating with the reservoir whereby air pressure differentials resulting from rotation of the fan cause the condensation in the reservoir to circulate within the reservoir and through the sluiceways eliminating pockets of cold condensation.
Claim 6
Independent Claim
131 words
The method of preventing exterior condensation in an air conditioning unit, said unit being divided by a partition into an evaporator section containing an evaporator on which condensation is formed and a condenser containing a condenser and a rotatable condenser fan, and the unit having a motor to rotate the fan, which comprises: locating a reservoir in the condenser section of the unit; transferring condensate from the evaporator to the reservoir; dividing the reservoir into two parts with a condenser fan shroud containing an opening for the condenser fan; and providing sluiceways in the condenser fan shroud communicating with the reservoir whereby air pressure differentials resulting from rotation of the fan cause the condensation in the reservoir to circulate within the reservoir and through the sluiceways eliminating pockets of cold condensation.
Claim 7
Dependent Claim
34 words
The method as set forth in claim 4 wherein the step of providing sluiceways includes having two sluiceways one on each side of the opening for the condenser fan in the condenser fan shroud.
