Abstract

An air conditioning unit including a basepan upon which is mounted an indoor section in communication with the space to be conditioned. The indoor section includes an indoor heat exchanger and means for circulating air to be conditioned in heat exchange relation with the indoor heat exchanger. Also mounted on the basepan is an outdoor section in communication with ambient air and including an outdoor heat exchanger and a compressor. A partition forms a part of the basepan and divides the air conditioning unit to separate the indoor section from the outdoor section. The partition is provided with a partition opening therethrough. Refrigerant carrying lines extend between the indoor section and the outdoor section through the partition opening. An elongated section of insulating material circumferentially encloses the refrigerant tubes in the region in which they pass through the partition opening. The insulating material is taped to the refrigerant tubes at the end thereof which is on the side of the partition opening adjacent to the outdoor section thereof.

Dependent claims

An air conditioning unit including a basepan which comprises:

an indoor section in communication with the space to be conditioned including an indoor heat exchanger and means for circulating air to be conditioned in heat exchange relation with the indoor heat exchanger;
an outdoor section in communication with ambient air and including an outdoor heat exchanger and a compressor;
a partition mounted to said basepan for dividing the air conditioning unit to separate said indoor section from said outdoor section, said partition further defining a partition opening;
at least two refrigerant carrying lines extending between said indoor section and said outdoor section through said partition opening;
and
an elongated length of sealing material, said material circumferentially enclosing the portion of said at least two refrigerant carrying lines adapted to extend through said partition opening, the circumference of said elongated length of sealing material being greater than the circumference of said partition opening;
and
tape means surrounding one end of said elongated length of sealing material for attaching said material to said refrigerant carrying lines on the side of said partition opening adjacent to the outside section and for creating a tapered transition having a circumference smaller than that of said elongated length of sealing material.
