Abstract

An insulating sleeve for a compressor discharge pipe is provided. The insulating sleeve includes a first half-sleeve having a first curved body portion and a first extended portion. The first curved body portion is configured to fit at least partially around a portion of the compressor discharge pipe. A second half-sleeve has a second curved body portion configured to attach to the first curved body portion such that the first and second curved body portions completely encircle the portion of the compressor discharge pipe. The second half-sleeve includes a second extended portion configured to attach to the first extended portion. Each of the first and second extended portions include respective first and second cavities which, together, encase a temperature sensor in contact with, or in spaced relation to, the compressor discharge pipe.

First claim

What is claimed is:

1. An insulating sleeve for a compressor discharge pipe, the insulating sleeve comprising:
a first half-sleeve having a first curved body portion and a first extended portion, wherein the first curved body portion is configured to fit at least partially around a portion of the compressor discharge pipe;
a second half-sleeve having a second curved body portion configured to attach to the first curved body portion such that the first and second curved body portions completely encircle the portion of the compressor discharge pipe, the second half-sleeve including a second extended portion configured to attach to the first extended portion, each of the first and second extended portions including respective first and second cavities which, together, encase a temperature sensor in contact with, or in spaced relation to, the compressor discharge pipe;
wherein the first and second half-sleeves are attached using one or more mechanical fasteners;
wherein the first and second half-sleeves are attached at a first end of the first and second half-sleeves proximate the first and second curved body portions, and attached at a second end of the first and second half-sleeves proximate the first and second extended portions; and
wherein the first half-sleeve has an opening at each of the first and second ends, each opening configured for the insertion of a screw therethrough, and wherein the second half-sleeve has a threaded opening at each of the first and second ends, each opening configured to receive a threaded portion of the screw.

2. The insulating sleeve of claim 1 , wherein the first and second half-sleeves are each constructed from molded plastic.

3. The insulating sleeve of claim 1 , wherein the one or more mechanical fasteners includes a threaded screw.

4. The insulating sleeve of claim 1 , wherein at least one of the first and second extended portions includes at least a partial opening for a wire connected to the temperature sensor, the at least partial opening providing a path from its respective cavity to an exterior of the first or second half-sleeve.

5. An insulating sleeve for a compressor discharge pipe, the insulating sleeve comprising:
a second body portion configured to fit at least partially around a first segment of the compressor discharge pipe; and
a first portion configured to fit at least partially around a second segment of the compressor discharge pipe different from the first segment of the compressor discharge pipe;
wherein the first portion is further configured to be removably attached to the second body portion to secure the insulating sleeve to the discharge pipe such that the second body portion and first portion completely encircle the compressor discharge pipe, the second body portion including an extended section with a cavity configured to encase a temperature sensor in contact with, or in spaced relation to, the compressor discharge pipe; and
wherein an attachment mechanism for the first portion and second body portion comprises a cable strap pivotably attached to the second body portion.

6. The insulating sleeve of claim 5 , wherein the cable strap wraps partially around the discharge pipe to secure the compressor discharge pipe to the second body portion.

7. An insulating sleeve for a compressor discharge pipe, the insulating sleeve comprising:
a second body portion configured to fit at least partially around a first segment of the compressor discharge pipe; and
a first portion configured to fit at least partially around a second segment of the compressor discharge pipe different from the first segment of the compressor discharge pipe;
wherein the first portion is further configured to be removably attached to the second body portion to secure the insulating sleeve to the discharge pipe such that the second body portion and first portion completely encircle the compressor discharge pipe, the second body portion including an extended section with a cavity configured to encase a temperature sensor in contact with, or in spaced relation to, the compressor discharge pipe;
wherein the first portion is a separate member from the second body portion, the first portion and second body portion configured to be attached via one or more posts in a first flange on the first portion, each of the one or more posts inserted through a respective hole in a second flange on the second body portion, and secured via an “E” spring clip, which is fastened to a groove encircling its respective post.

8. An insulating sleeve for a compressor discharge pipe, the insulating sleeve comprising:
a second body portion configured to fit at least partially around a first segment of the compressor discharge pipe; and
a first portion configured to fit at least partially around a second segment of the compressor discharge pipe different from the first segment of the compressor discharge pipe;
wherein the first portion is further configured to be removably attached to the second body portion to secure the insulating sleeve to the discharge pipe such that the second body portion and first portion completely encircle the compressor discharge pipe, the second body portion including an extended section with a cavity configured to encase a temperature sensor in contact with, or in spaced relation to, the compressor discharge pipe; and
wherein the first portion has a threaded opening to receive a tension screw, the second body portion having two arms that extend to opposite sides of the compressor discharge pipe, the second body portion having a pin at the end of each of the two arms, wherein the first portion has two curved ends, each configure to wrap around one of the pins such that rotation of the tension screw in a first direction tightens the attachment between the first portion and second body portion, and rotation of the tension screw in a second direction opposite the first direction loosens the attachment between the first portion and second body portion.

9. An insulating sleeve for a compressor discharge pipe, the insulating sleeve comprising:
a second body portion configured to fit at least partially around a first segment of the compressor discharge pipe; and
a first portion configured to fit at least partially around a second segment of the compressor discharge pipe different from the first segment of the compressor discharge pipe;
wherein the first portion is further configured to be removably attached to the second body portion to secure the insulating sleeve to the discharge pipe such that the second body portion and first portion completely encircle the compressor discharge pipe, the second body portion including an extended section with a cavity configured to encase a temperature sensor in contact with, or in spaced relation to, the compressor discharge pipe; and
wherein the first portion has a threaded opening to receive a tension screw, the second body portion having two arms that extend to opposite sides of the compressor discharge pipe, the second body portion having a first hook at the end of each of the two arms, wherein the first portion has, at each end, a second hook configured to interlock with the first hook, such that rotation of the tension screw in a first direction tightens the attachment between the first portion and second body portion, and rotation of the tension screw in a second direction opposite the first direction loosens the attachment between the first portion and second body portion.

10. An insulating sleeve for a compressor discharge pipe, the insulating sleeve comprising:
a second body portion configured to fit at least partially around a first segment of the compressor discharge pipe; and
a first portion configured to fit at least partially around a sec
