Abstract:
A comb-like insert having a body and plurality of tapered fingers is installed with its fingers disposed within respective minichannels. The fingers and their respective minichannels are so sized as to restrict the channels and frictionally hold the insert in place in one dimension while providing for gaps in another dimension such that the flow of refrigerant is somewhat obstructed but allowed to pass through the gaps between the insert fingers and the minichannel walls and then expand as it passes along the tapered fingers to thereby provide a more homogenous mixture to the individual minichannels. A provision is also made to hold the insert in its installed position by way of internal structure within the inlet manifold. In one embodiment, an internal plate is provided for that purpose, and the plate has openings formed therein for the equalization of pressure on either side thereof.

Igor B. Vaisman - West Hartford CT, US
Parmesh Verma - Manchester CT, US
Gary D. Winch - Colchester CT, US
Joseph J. Sangiovanni - West Suffield CT, US
Assignee:
Carrier Corporation - Farmington CT
International Classification:
F28F 9/22
US Classification:
165174
Abstract:
A heat exchanger includes a plurality of multi-channel heat exchange tubes extending between spaced inlet and outlet headers. Each heat exchange tube has a plurality of flow channels defining discrete flow paths extending longitudinally in parallel relationship from its inlet end to its outlet end. The inlet header has a channel for receiving a two-phase fluid from a fluid circuit and a chamber for collecting the fluid. The chamber has an inlet in flow communication with the channel and an outlet in flow communication with the plurality of fluid flow paths of the heat exchange tubes. The channel defines a relatively high turbulence flow passage that induces uniform mixing of the liquid phase refrigerant and the vapor phase fluid and reduces potential stratification of the vapor phase and the liquid phase within the fluid passing through the header.

Thermally Activated High Efficiency Heat Pump

View page
US Patent:
8297065, Oct 30, 2012
Filed:
Aug 28, 2007
Appl. No.:
12/675212
Inventors:
Igor B. Vaisman - West Hartford CT, US
Michael F. Taras - Fayetteville NY, US
Joseph J. Sangiovanni - West Suffield CT, US
Assignee:
Carrier Corporation - Farmington CT
International Classification:
F25B 1/00
US Classification:
62115, 62470, 62498, 62503
Abstract:
A vapor compression cycle system is combined with a Rankine cycle system, with the two systems having a common suction accumulator from which the compressor draws refrigerant vapor for the vapor compression cycle system and from which a pump draws liquid refrigerant for circulation within the Rankine cycle system. The vapor from the Rankine cycle system expander is passed to the compressor discharge to provide a mixture which is circulated within the vapor compression cycle system to obtain improved performance. The heat exchangers are sized so as to obtain a non-complete evaporation, with the resulting two-phase fluid passing to the suction accumulator to provide liquid refrigerant to the Rankine cycle system and vapor refrigerant to the vapor compression cycle system.
