Abstract
Abstract A method and apparatus for simulating the normal and abnormal operating conditions in an air-conditioning system comprising a plurality of mechanically and electrically operated working units functionally interconnected into a thermodynamic loop, including a plurality of simulating components responsive to control signals from a central control station for simulating desired conditions. The station includes a female receptacle for receiving a programmed plug-in board thereby automatically and simultaneously affecting the state of energization of certain of the simulating components and working units whereby certain of the working units will operate in an abnormal mode.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
146 words
A method for training air-conditioning students in simulating normal and abnormal operating modes in an air-conditioning system, comprising the steps of: interconnecting a plurality of working units and simulating components to form an operative thermodynamic loop, said simulating and working units being arranged in respective simulating electric circuits and working electric circuits and each circuit having a terminal originating at a control station including a receptacle; electrically energizing said loop; consecutively inserting programmed members into said receptacle, each programmed member having circuit arrangements thereon; and transmitting control signals from said receptacle to thereby simultaneously control the operating conditions of said simulating and working electric circuits whereby a simulated mode of operation is created for a particular one of said working units to allow the trainee an opportunity to diagnose the nature of said normal and abnormal modes of operation as well as the resulting manifestations thereof.
Claim 2
Independent Claim
146 words
A method for training air-conditioning students in simulating normal and abnormal operating modes in an air-conditioning system, comprising the steps of: interconnecting a plurality of working units and simulating components to form an operative thermodynamic loop, said simulating and working units being arranged in respective simulating electric circuits and working electric circuits and each circuit having a terminal originating at a control station including a receptacle; electrically energizing said loop; consecutively inserting programmed members into said receptacle, each programmed member having circuit arrangements thereon; and transmitting control signals from said receptacle to thereby simultaneously control the operating conditions of said simulating and working electric circuits whereby a simulated mode of operation is created for a particular one of said working units to allow the trainee an opportunity to diagnose the nature of said normal and abnormal modes of operation as well as the resulting manifestations thereof.
Claim 3
Dependent Claim
175 words
An air conditioning training apparatus for simulating normal and abnormal operating modes, unknown to the trainee in an air-conditioning system comprising: a plurality of working units functionally interconnected to form an operative thermodynamic loop when energized by a source of electric power, said loop including a plurality of suitably arranged, simulating components responsive to control signals for simulating the abnormal mode of operation of certain ones of said working units; a central control station for generating such control signals including a receptacle, said simulating and working units being arranged in respective simulating and working circuits each of which having a terminal originating at said control station; at least one programmed member matingly engageable with said receptacle and having circuit arrangements thereon adapted to simultaneously control the operating conditions of said simulating and working electric circuits whereby a simulated mode of operation is created for a particular one of said working units to allow the trainee an opportunity to diagnose the nature of said unknown abnormal mode of operation as well as the resulting manifestations thereof.
Claim 4
Dependent Claim
175 words
An air conditioning training apparatus for simulating normal and abnormal operating modes, unknown to the trainee in an air-conditioning system comprising: a plurality of working units functionally interconnected to form an operative thermodynamic loop when energized by a source of electric power, said loop including a plurality of suitably arranged, simulating components responsive to control signals for simulating the abnormal mode of operation of certain ones of said working units; a central control station for generating such control signals including a receptacle, said simulating and working units being arranged in respective simulating and working circuits each of which having a terminal originating at said control station; at least one programmed member matingly engageable with said receptacle and having circuit arrangements thereon adapted to simultaneously control the operating conditions of said simulating and working electric circuits whereby a simulated mode of operation is created for a particular one of said working units to allow the trainee an opportunity to diagnose the nature of said unknown abnormal mode of operation as well as the resulting manifestations thereof.
Claim 5
Dependent Claim
