Abstract
Abstract A system for use in multiple occupancy buildings wherein energy consumption for comfort heating or cooling is centrally metered to provide an indication of relative amounts of energy used by the individual occupancy units. An electrically operated elapsed time meter is associated with each occupancy unit having its own individual temperature control unit. The meter is actuated to record the time for which the temperature control unit is operating to consume energy for room heating or cooling purposes.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
A system for indicating relative amounts of energy consumed for comfort temperature control by individual occupancy units of a multi-unit structure wherein the actual total energy use is metered for the entire structure, said system comprising: a. a plurality of temperature control units, each associated with one of the individual occupancy units to alter the temperature of room air therein, and all operated from a common energy source; b. a control switch associated with each of said temperature control units, the latter being operable by energy from the common source to alter room air temperature in accordance with the selective setting of said control switch; c. an electrically operated elapsed time meter associated with each of said temperature control units; and d. means for actuating said meter to indicate the elapsed time of operation of its associated temperature control unit to alter room air temperature.
Claim 2
Independent Claim
145 words
A system for indicating relative amounts of energy consumed for comfort temperature control by individual occupancy units of a multi-unit structure wherein the actual total energy use is metered for the entire structure, said system comprising: a. a plurality of temperature control units, each associated with one of the individual occupancy units to alter the temperature of room air therein, and all operated from a common energy source; b. a control switch associated with each of said temperature control units, the latter being operable by energy from the common source to alter room air temperature in accordance with the selective setting of said control switch; c. an electrically operated elapsed time meter associated with each of said temperature control units; and d. means for actuating said meter to indicate the elapsed time of operation of its associated temperature control unit to alter room air temperature.
Claim 3
Dependent Claim
31 words
The invention according to claim 1 wherein said actuating means comprising a normally open relay which closes to actuate said elapsed time meter in response to closure of said control switch.
Claim 4
Dependent Claim
27 words
The invention according to claim 2 wherein said control switch comprises a thermostat sensitive to the room temperature of the occupancy unit with which it is associated.
Claim 5
Dependent Claim
27 words
The invention according to claim 3 wherein said common energy source is an electrical power supply and each of said temperature control units includes a refrigerant compressor.
Claim 6
Dependent Claim
18 words
The invention according to claim 4 wherein said temperature control units each further include an electrical resistance heater.
Claim 7
Dependent Claim
44 words
The invention according to claim 3 wherein said common energy source includes an electrical power supply and a combustible fuel, and each of said temperature control units includes a furnace for burning said fuel and a refrigerant compressor operated by said electrical power supply.
Claim 8
Dependent Claim
36 words
The invention according to claim 6 wherein said actuating means further comprises a temperature sensitive switch operable to actuate said elapsed time meter in response to the temperature in said furnace rising above a predetermined value.
Claim 9
Dependent Claim
26 words
The invention according to claim 1 and further including signal means operable in response to cumulative actuation of said elapsed time meter for a pre-selected time.
Claim 10
Dependent Claim
26 words
The invention according to claim 1 wherein said temperature control units each include a heat exchanger through which a medium is circulated to alter air temperature.
Claim 11
Dependent Claim
30 words
The invention according to claim 9 wherein said control switch comprises a differential thermostat responsive to the difference in temperature of said medium when entering and leaving said heat exchanger.
