Abstract
An environmental control unit, such as an HVAC or heat pump unit, includes a housing, and a blower disposed in the housing, the blower configured to draw air into the housing via an air inlet and exhaust air from the housing via an air outlet. The unit includes a heat exchanger disposed in the housing between the air inlet and the blower, and a compressor disposed within housing. The unit include features that reduce noise emitted from the compressor. The noise reduction features include a noise-reducing enclosure that encapsulates the compressor. The enclosure includes a rigid metal shell, an outer insulating structure fixed to an outside surface of the shell, and an inner insulating structure fixed to an inside surface of the shell.
