Abstract

A pre-packaged air conditioning system for providing heating, cooling, ventilation and energy recovery, the system comprising: an energy recovery ventilator, condenser, condenser fan, compressor, expansion device, flow reversing valve, evaporator and evaporator fan; an inlet for providing outside air to the evaporator, the inlet for extending beyond a wall of a host structure; and an exhaust duct for exhausting air outside of the host structure, the exhaust duct for extending beyond a wall to the host structure; wherein the energy recovery ventilator, condenser, condenser fan, compressor, evaporator and evaporator fan are housed within a single envelope configured for installation inside the host structure.

1 . A pre-packaged air conditioning system for providing heating, cooling, ventilation and energy recovery, the system comprising:
 an energy recovery ventilator, condenser, condenser fan, compressor, expansion device, flow reversing valve, evaporator and evaporator fan;   an inlet for providing outside air to the evaporator, the inlet for extending beyond a wall of a host structure; and   an exhaust duct for exhausting air outside of the host structure, the exhaust duct for extending beyond a wall to the host structure;   wherein the energy recovery ventilator, condenser, condenser fan, compressor, expansion device, flow reversing valve, evaporator and evaporator fan are housed within a single envelope configured for installation inside the host structure.   
     
     
         2 . The pre-packaged air conditioning system of  claim 1 , wherein outside air supplied to the energy recovery ventilator is acquired through the inlet, and wherein airflow over the condenser exits through the exhaust duct. 
     
     
         3 . The pre-packaged air conditioning system of  claim 1 , wherein the energy recovery ventilator recovers thermal energy from a stream of exhaust air. 
     
     
         4 . The pre-packaged air conditioning system of  claim 1 , wherein the energy recovery ventilator transfers thermal energy and moisture to an outside air stream. 
     
     
         5 . The pre-packaged air conditioning system of  claim 1 , wherein the energy recovery ventilator comprises a membrane to recapture water from exhaust air and transfer moisture to an outside air stream. 
     
     
         6 . The pre-packaged air conditioning system of  claim 1 , wherein the energy recovery ventilator comprises a rotating wheel or cross-flow core heat exchanger to recover energy. 
     
     
         7 . The pre-packaged air conditioning system of  claim 1 , wherein the system has a volume of between six and fifteen cubic feet. 
     
     
         8 . The pre-packaged air conditioning system of  claim 1 , wherein the system has a capacity of between of five and twenty four thousand BTUs. 
     
     
         9 . The pre-packaged air conditioning system of  claim 1 , wherein the pre-packaged HVAC system comprises a sealed container enveloping the condenser, condenser fan, compressor, expansion device, flow reversing valve, evaporator and evaporator fan, with a single inlet and a single outlet. 
     
     
         10 . The pre-packaged air conditioning system of  claim 1 , further comprising:
 a splitter receiving outside air and dividing the outside air into an outside air stream directed to the evaporator and a condenser stream directed to the condenser.   
     
     
         11 . The pre-packaged air conditioning system of  claim 1 , wherein:
 the splitter includes an inlet core damper controlling the outside air stream to the evaporator and a bypass damper controlling the condenser stream to the condenser.   
     
     
         12 . The pre-packaged air conditioning system of  claim 1 , wherein:
 the energy recovery ventilator is positioned in a housing;   the evaporator and condenser are positioned in a cabinet;   the housing being mounted to the cabinet to define the single envelope.   
     
     
         13 . The pre-packaged air conditioning system of  claim 12 , wherein:
 the housing and cabinet include openings to allow outside air and return air to flow from the cabinet to the housing.   the housing and cabinet include openings to allow supply air and exhaust air to flow from the housing to the cabinet.   
     
     
         14 . The pre-packaged air conditioning system of  claim 13 , wherein:
 the openings are joined by ducts.   
     
     
         15 . The pre-packaged air conditioning system of  claim 12 , wherein:
 the ducts are positioned internal to the cabinet.   
     
     
         16 . The pre-packaged air conditioning system of  claim 12 , wherein:
 the ducts are positioned external to the cabinet.
