CLIMATE CONTROL SYSTEM FOR MACHINE CABIN

摘要

A climate control system is provided for use with a machine. The climate control system may have a compressor electrically powered to compress refrigerant, a condenser configured to dissipate heat from compressed refrigerant, and an evaporator configured to dissipate heat from chilled refrigerant to air directed into a cabin. The climate control system may also have at least one blower configured to selectively direct ambient air, cabin air, or a combination of ambient and cabin air through the evaporator, and a controller in communication with the engine, the compressor, and the at least one blower. The controller may be configured to determine a status of an engine, to determine existence of an operator in the cabin, and to selectively cause the at least one blower to direct only cabin air through the evaporator into the cabin when the engine is shut down and the operator is present in the cabin.

1. A climate control system for a machine having an engine and a cabin, the climate control system comprising:
a compressor electrically powered to compress a refrigerant; a condenser configured to dissipate heat from compressed refrigerant to the atmosphere; an evaporator configured to dissipate heat from chilled refrigerant to air directed into the cabin; at least one blower configured to selectively direct ambient air, cabin air, or a combination of ambient and cabin air through the evaporator and into the cabin; and a controller in communication with the engine, the compressor, and the at least one blower, the controller being configured to:
determine a status of the engine;determine existence of an operator within the cabin; andselectively cause the at least one blower to direct only cabin air through the evaporator and into the cabin when the engine is shut down and the operator is present in the cabin.
