Abstract

A high efficiency cooling and heating apparatus comprises an outdoor condensing unit having a high speed fan disposed within a housing. Also disposed with the housing is a micro compressor run by a high speed brushless DC motor with a custom winding to increase efficiency and decrease weight. A control circuit allows the motor to operate at high speeds almost instantaneously. The fan pulls air across a dual condenser coil disposed within the housing. An indoor evaporative unit also houses a high speed fan along with a control circuit to allow an operator to select cooling or heating an air flow. The indoor and out door units are connected with hoses to provide heat exchange. The apparatus can be operated at a much higher ambient temperature than conventional air cooling and heating systems.

Claims

exact text as granted — not AI-modified
1 . A high efficiency cooling and heating apparatus comprises:
 a first housing;   a condenser coil disposed within said first housing;   a fan mounted in front of said condenser coil;   said fan arranged to pull air through said condenser coil;   a high speed brushless DC motor disposed within said first housing;   a micro compressor disposed within said first housing and driven by said high speed brushless DC motor;   a heat exchanging unit in thermodynamic communication with said micro compressor; and   a control circuit in electrical communication with said fan and said high speed brushless motor.   
   
   
       2 . The high efficiency cooling and heating apparatus according to  claim 1  wherein said first housing is made of aluminum. 
   
   
       3 . The high efficiency cooling and heating apparatus according to  claim 1  wherein said high speed brushless DC motor is designed with a custom winding to achieve up to 7,600 revolution per minute. 
   
   
       4 . The high efficiency cooling and heating apparatus according to  claim 3  wherein said control circuit is adapted to allow said high speed brushless DC motor to operate at a high speed as soon as unit is switched on. 
   
   
       5 . The high efficiency cooling and heating apparatus according to  claim 1  wherein said condenser coil is filled with a super efficient refrigerant. 
   
   
       6 . The high efficiency cooling and heating apparatus according to  claim 5  wherein said super efficient refrigerant is Ikon B. 
   
   
       7 . The high efficiency cooling and heating apparatus according to  claim 5  wherein said super efficient refrigerant is R132a. 
   
   
       8 . The high efficiency cooling and heating apparatus according to  claim 1  further comprising a switching means for switching said high efficiency cooling and heating apparatus from operating in a cooling or heating mode. 
   
   
       9 . The high efficiency cooling and heating apparatus according to  claim 8  wherein said switching means is a solenoid. 
   
   
       10 . The high efficiency cooling and heating apparatus according to  claim 1  wherein said high speed brushless DC motor has a coefficient of performance of approximately 3.5. 
   
   
       11 . The high efficiency cooling and heating apparatus according to  claim 1  wherein said heat exchanging unit further comprises:
 a second housing;   a heat exchanging coil disposed within said second housing; and   a DC powered fan mounted in front of said heat exchanging coil.
