A method and system are described for a refrigerant distributor, and for attaching the distributor tubes to an evaporator coil. A short tube can inserted into the bell end of a tube and the hell end can be crimped around the short tube to lock it into place. The short tube preferably has a bead or widened shaft around which to crimp the bell. The disclosure is particularly beneficial for aluminum based components because aluminum is more susceptible to blockages or leaking due to problems from brazing.

This disclosure presents a heat exchanger that comprises a header frame having end plates, a plurality of rows of finned hairpins, each extending through a cooling fin and each having ends extending through the end plates, and at least one finless hairpin having ends extending through the end plates. Additionally, a support sheet is coupled to the header frame and at least on finless hairpin extends through the support sheet and is supported thereby. A method of manufacturing the heat exchanger is also presented as well as a heat ventilation air conditioning system in which the heat exchanger may be employed.

Hybrid heat exchanger

This disclosure presents a heat exchanger that comprises a header frame having end plates, a plurality of rows of finned hairpins, each extending through a cooling fin and each having ends extending through the end plates, and at least one finless hairpin having ends extending through the end plates. A method of manufacturing the heat exchanger is also presented as well as a heat ventilation air conditioning system in which the heat exchanger may be employed.

One aspect of this disclosure provides a refrigerant charge compensator having an increased heat transfer surface. The housing has an internal volume and first and second ports for allowing a passage of refrigerant therethrough. The internal volume is partitioned into an indirect refrigerant passageway that extends through the housing and a refrigerant storage area. The refrigerant storage area has a storage access port and is in contact with the indirect refrigerant passageway. Also a heat pump system implementing the compensator is provided and a method of manufacturing the compensator is provided.
