Claim 5:
6. The refrigerant leak detection system of claim 1, wherein the controller is configured to determine a speed of sound using the following computation:, S
          =
          
            
              (
              
                X
                ⁢
                2
                ⁢
                L
              
              )
            
            
              Δ
              ⁢
              T
            
          
        
        ,, where S is the speed of sound in the space, L is a distance between the transmitter, X is a predetermined number of echoes that the acoustic wave experiences during the time of flight and the receiver, and ΔT is the time of flight.
