Power managing method and system for transportation refrigeration unit
A power management method used for power distribution in a transportation refrigeration unit. The power management method includes calculating engine power according to engine operating parameters; calculating power generator real-time input power according to power generator excitation current; calculating available power based on the power generator real-time input power and the engine power; and managing power distributed to a compressor based on the available power. The present invention further relates to a power management system. The power management method and system have the advantages of simplicity, reliability, stable operation and the like, the power generator real-time input power can be calculated according to the power generator excitation current, thus more power can be provided to the compressor on the premise that the power supply to power generator loads is guaranteed, and the operating efficiency of the transportation refrigeration unit is improved.
REDUCTION OF CONDENSATION IN VEHICLE HVAC SYSTEMS
A vehicle heating, ventilating, and air conditioning (HVAC) system can be configured to reduce and/or prevent condensation build up on one or more elements of the system. Subsequent to a power state of the vehicle being switched from an active state to an inactive state, a fresh mode air source can be selected as an intake for a blower. It can be determined whether an ambient temperature is greater than or equal to a predetermined temperature. It can then be determined whether the compressor was in operation prior to the vehicle having been switched from the active state to the inactive state. It can be determined whether a temperature of an evaporator of the HVAC system is rising. If it is determined that the ambient temperature is greater than or equal to the predetermined temperature value, that the compressor was in operation prior to the vehicle having been switched from the active state tot eh inactive state, and that the temperature of the evaporator is rising, a blower can be activated to blow air from the fresh mode air source across the evaporator.
AIR-CONDITIONING SYSTEM FOR A MACHINE
An air-conditioning system including a primary circuit and a secondary circuit is provided. The primary circuit includes a flow of refrigerant, an evaporator and a chiller configured to exchange heat between a coolant and the refrigerant. The secondary circuit includes a heat exchanger in fluid communication with the chiller to receive the coolant. The heat exchanger includes a phase change material in heat exchange relationship with the coolant, such that the coolant exchanges heat with the phase change material to store thermal energy in the phase change material. The air-conditioning system is implemented in a machine in which during an idle-off state, the stored energy in the heat exchanger is discharged to provide an air-conditioning effect.
External noise reduction of HVAC system for a vehicle
A HVAC system for a vehicle that includes a propulsion system, a frame, a passenger compartment, and a door coupled to the frame.
