Appl. No.:

10/936247

Inventors:

John Reason - Liverpool NY, US
Awwad Nader - Baldwinsville NY, US

Assignee:

Carrier Corporation - Syracuse NY

International Classification:

F25D021/08

US Classification:

62155, 62222, 62234, 62276

Abstract:

A refrigerant cycle is provided with a transient mode for moving from a defrost cycle back to steady state operation. In particular, some default position of the expansion device is selected when defrost cycle ends. The evaporator is hot at the end of defrost cycle, and might otherwise suggest an increased flow of refrigerant through the expansion device, which could be undesirable. Thus, a control for the inventive system moves the expansion device to a defrost transient position, with the defrost transient position restricting the flow of refrigerant to a value that would be less than that dictated by the high temperature of the evaporator. At some period of time after the end of the defrost mode, the refrigerant cycle can be returned to state steady operation.

Assignee:

Carrier Corporation - Farmington CT

International Classification:

F25B 49/00
F25B 27/00
H01R 39/46
H02P 27/00
G01R 25/00

US Classification:

62126, 623233, 318439, 318799

Abstract:

In a transport refrigeration system which is susceptible to having its drive motors connected to a power source in reverse phase relationship to thereby operate the drive motors in reverse, provision is made to measure the current flow to the motors during operation in each direction and for comparing those current flows to determine which is greater and therefore representative of operation in the proper direction. A backup method is also provided for sensing the ambient temperature of the air downstream of the condenser coil, both before and during motor operation to determine whether the temperature during motor operation is greater than that prior to operation to thereby indicate a proper connection.

Appl. No.:

12/521315

Inventors:

Nader S. Awwad - Baldwinsville NY, US
John R. Reason - Liverpool NY, US

Assignee:

Carrier Corporation - Farmington CT

International Classification:

F25B 41/04

US Classification:

62225

Abstract:

A refrigerated transport system has a container, a generator system, and a refrigeration system. The refrigeration system is electrically coupled to the generator to receive electric power and thermally coupled to the container. The refrigeration system includes an electrically powered compressor. A condenser is downstream of the compressor along a refrigerant flowpath. An expansión device is downstream of the compressor along the refrigerant flowpath. An evaporator is downstream of the expansión device along the refrigerant flowpath. A controller is coupled to the expansión device to control operation of the expansión device. The controller is configured to opérate the expansión device to control an evaporator superheat. The evaporator superheat is to be relatively high for a set temperature of a first valué associated with non-frozen perishables. The evaporator superheat is to be relatively low for a second valué of the temperature associated with frozen goods and subject to maintenance of a minimum suction superheat.

International Classification:

G01M 15/04

US Classification:

7311431

Abstract:

A sensor that is designed for determining ambient pressure for purposes of derating an internal combustion engine at high altitudes, is used to determine the condition of the air filter by taking pressure measurements in the intake manifold before and after the engine is started, with the difference then being an indication of the condition of the air filter.

US Classification:

62 61, 62115, 62134, 62180

Abstract:

A transport refrigeration system has an engine driving an electric generator. A compressor is powered by the generator. At least one first electric fan is positioned to drive an airflow across a heat rejection heat exchanger. At least one second electric fan is positioned to drive an airflow across a heat absorption heat exchanger. A controller is coupled to the compressor and first and second fans. The controller is configured to: start the engine; engage the generator and at least one of the first fans before the engine has reached running speed; after the engine has reached running speed, start the compressor; and after starting the compressor, start at least one of the second fans.
