Abstract
A capillary tube for a heat pump system, such as a packaged terminal air conditioner unit, includes features for adjusting a restriction on a flow of refrigerant through the capillary tube depending upon a direction of the flow of refrigerant through the capillary tube. A related packaged terminal air conditioner unit is also provided.
Claims20
A packaged terminal air conditioner unit, comprising:
- a casing extending between an exterior side portion and an interior side portion;
- a compressor positioned within the casing, the compressor operable to compress a refrigerant;
- an interior coil positioned within the casing at the interior side portion of the casing;
- an exterior coil positioned within the casing at the exterior side portion of the casing;
- a reversing valve in fluid communication with the compressor in order to receive compressed refrigerant from the compressor, the reversing valve configured for selectively directing the compressed refrigerant from the compressor to either the interior coil or the exterior coil;
- a capillary tube extending between the interior coil and the exterior coil in order to direct refrigerant between the interior coil and the exterior coil, the capillary tube comprising means for adjusting a restriction on a flow of refrigerant through the capillary tube depending upon a direction of the flow of refrigerant through the capillary tube.
3 more elements
A packaged terminal air conditioner unit, comprising:
- a casing;
- a compressor positioned within the casing, the compressor operable to increase a pressure of a refrigerant;
- a reversing valve positioned within the casing, the reversing valve in fluid communication with the compressor in order to receive compressed refrigerant from the compressor;
- an interior coil positioned within the casing;
- an exterior coil positioned within the casing opposite the interior coil, the interior coil and the exterior coil in fluid communication with the reversing valve such that either the interior coil or the exterior coil receive the compressed refrigerant from the reversing valve;
- and
- a capillary tube extending between the interior coil and the exterior coil in order to direct refrigerant between the interior coil and the exterior coil, the capillary tube extending between a first end portion and a second end portion, the first end portion of the capillary tube positioned adjacent the exterior coil, the second end portion of the capillary tube positioned adjacent the interior coil, the capillary tube defining an interior volume for directing the flow of refrigerant through the capillary tube;
- and
- a block positioned within the interior volume of the capillary tube at the first end portion of the capillary tube such that the block occupies a portion of the interior volume of the tubular body at the first end portion of the tubular body.
6 more elements
A capillary tube for a heat pump system, comprising:
- a tubular body extending between a first end portion and a second end portion, the tubular body defining an interior volume for directing a flow of refrigerant through the tubular body, cross-sections of the interior volume of the tubular body being substantially constant between the first and second end portions of the tubular body;
- a block positioned within the interior volume of the tubular body at the first end portion of the tubular body such that the block occupies a portion of the interior volume of the tubular body at the first end portion of the tubular body.
