A thermal management system for a vehicle includes an enclosure containing an air-handling unit, a first circuit, a second circuit, and a control interface module. The air-handling unit includes a housing and a variable speed blower configured to provide a flow of air through the housing. The first circuit includes a compressor, a condenser in thermal communication with the air-handling unit, a receiver-drier, an expansion valve, and a chiller, in series. The second circuit includes a first loop including the chiller of the first circuit, a second loop including a radiator in thermal communication with the air-handling unit, and a third loop including a heater. The control interface module is configured to control each of the air-handling unit, the first circuit, and the second circuit.
