Abstract
A compact freezer unit for supplying conditioned air to the interior of a structure is provided herein. The compact freezer unit includes a housing containing one or more components of the freezer unit, the housing having dimensions of height, width, and depth. The components include an evaporator comprising one or more coils and an evaporator fan, a condenser and a condenser fan, a Direct Current (DC) Enhanced Vapor Injection (EVI) inverter compressor, an economizer for separating liquid and vapor refrigerant, a 4-way valve and a chassis belt electric heater configured to defrost one or more surfaces, one or more sensors for sensing a condition and generating an output signal received by a controller, and a plurality of refrigerant lines fluidly connecting the condenser and the evaporator.

A compact freezer unit for supplying conditioned air to an interior of a structure, the compact freezer unit comprising:
- a housing containing one or more components of the freezer unit, the housing having dimensions of height, width, and depth, wherein at least two of the dimensions are less than 35 inches,
- the components comprising:
- an evaporator comprising one or more coils and an evaporator fan;
- a condenser and a condenser fan;
- a Direct Current (DC) Enhanced Vapor Injection (EVI) inverter compressor;
- an economizer for separating liquid and vapor refrigerant;
- a 4-way valve and a chassis belt electric heater configured to defrost one or more surfaces;
- one or more sensors for sensing a condition and generating an output signal received by a controller;
- a plurality of refrigerant lines fluidly connecting the condenser and the evaporator;
- and
- wherein the unit is capable of producing conditioned air having a temperature of 10° F. or lower when the conditioned air exits the compact freezer unit.
