Abstract:
Systems and methods are directed to controlling the amount of power supplied by an engine for a transport refrigeration system (TRS). An engine load is estimated and compared with a maximum allowable power supply from an engine. The engine load can be automatically adjusted according to results of the comparison. An automatic adjustment of the amount of power supplied by the engine is provided, to ensure that the engine is operating within a preset window of operation and compliant with emission legislation.
Abstract:
A power supply system for a transport refrigeration system (20) includes an engine (26) coupled to a compressor (32) of a refrigeration unit for direct drive powering the compressor (32) and a generator (24) arranged to also be direct driven by the engine (26) for generating electric power. The generator (24) and the compressor (32) are mounted to a common drive shaft (25) driven by the engine (26), and the generator (24) may be integrated with the compressor (32). The power supply system may further include an alternator (50) arranged to be belt driven by the engine (26) for generating DC electric power. A battery pack (28) may be provided for storing and supplying additional DC power. During peak load demand on the refrigeration unit (20), the engine (26) may be operated with the generator (24) switched off to directly drive the compressor (32) and direct current may be drawn from the battery pack (28) to drive the condenser/gas cooler and evaporator fans (40, 44).
Abstract:
An air purifier (10) for an animal transport vehicle, such as a horse float (12), has a first air flow passageway (22) for receiving air and directing it in a first direction, and a second air flow passageway (40) continuous with the first air flow passageway and adapted to direct air received from the first air flow passageway in a second direction substantially opposite to the first direction. There is a bend region (42) joining the first and second air flow passageways where the change in the direction of air occurs. An air egress passageway (34) has an opening (36) adjacent the bend region so as to divert some of the air therethrough. The passageway (34) is so configured as to create a venturi effect on the diverted air. A filter (43) is located downstream of the second air flow passageway (40) and is mounted across an opening of the transport vehicle so that air flowing through the second air flow passageway is filtered before entering the transport vehicle.

A channel (16) having an inlet (14) and an outlet (15) for conducting air through said channel is formed in an insulation (11) material comprised in one (4) of said outer walls. A ventilator (17) arranged to create a forced airflow in said channel. At least one of said absorber, condenser and water separator is arranged between said inlet and outlet in said channel.
Abstract:
An air-conditioner, adapted to be fitted to a roof/wall of a vehicle, comprises: an external unit containing a compressor and at least one heat exchanger element and having air channels respectively for supplying conditioned air and for receiving return air through an opening in a roof or wall of the vehicle, the opening being either of two types of different sizes; a frame to be installed in the opening and between the external unit and the roof/wall and having locating elements, on each of two opposite sides of the frame, configured to locate the frame in the opening and to locate the frame in the external unit, wherein the frame is to be installed with the first side facing the roof or wall for the first type of opening and is to be installed with the first side facing the external unit for the second type of opening.
Abstract:
A transportation refrigeration system is provided including a tractor cabin having an engine and an engine cooling system. A trailer is operably coupled to the tractor cabin. A transport refrigeration unit is configured to maintain a controller temperature environment of a portion of the trailer. The transport refrigeration unit is mounted to a front surface of the trailer adjacent the truck. A shield (50) is mounted to at least one of the tractor cabin, trailer, and transport refrigeration unit. The shield is configured to block an air flow path between an area (42) of discharge air from the engine cooling system and a condenser air inlet (32) of the transport refrigeration unit.
Abstract:
A solar-thermal powered recreational vehicle featuring a solar-thermal air conditioning system integrated with a solar clean energy system to provide a recreational vehicle having improved energy efficiency. In an embodiment employing the principles of the present invention, the solar-thermal powered recreational vehicle can comprise a clean energy system for providing electrical power to the recreational vehicle, whereby the clean energy system features one or more solar photovoltaic panels, a batter bank, and a generator operatively coupled to a hybrid inverter. The solar-thermal air conditioning system is powered by the clean energy system, with the solar-thermal air conditioning system featuring a solar-thermal collector panel functioning to superheat compressed refrigerant prior to the compressed refrigerant being transmitted to the condenser. Because the compressor is the most energy-intensive component in the traditional direct expansion AC system, the use of free solar energy by the present invention to reduce the work load on the compressor significantly reduces the overall energy requirements of the recreational vehicle, thereby providing a recreational vehicle capable of operating on solar and battery power alone for significant periods of time.
Abstract:
An air conditioning system for a vehicle having a roof, the air conditioning system having at least one air conditioning unit, with a first chamber and second chamber forming a conditioned air flow plenum having a configured S- shaped air flow path, and an outlet port configured to direct the air flow path in a substantially horizontal plane adjacent to the roof to disperse the air flow away from the air conditioning unit without the need for ducting.
Abstract:
A controller in a heat management system is capable of managing unlimited hydronic heat sources and unlimited heating zones, each located within a desired area and each controlled by temperature sensors in bi-directional electronic/electrical communication with the controller. A user interface can be included with the controller (or interact with the controller) and be in bi-directional electrical/electronic communication with the controller. In such a way, one or more users can manage the heating of domestic water and the heating of zones or areas in which the one or.more users live via the controller. The controller in the heat management system may be used for controlling hydronic heating systems installed in RV, marine and home applications.
