Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A system for measuring the thermal energy dissipated in each of a plurality of units, each having a separate fluid circulating circuit served from a common pressurized main, comprising: thermostatically controlled electric shut-off valves disposed in each fluid circuit; an automatic constant flow regulating orifice in each fluid circuit; means for generating electrical signals representative of the inlet and outlet temperatures of the fluid medium in each circuit; and a digital computer connected to each of the shut-off valves and operative to receive the electric signals representative of the inlet and outlet fluid temperatures from each circuit, the computer being programmed to successively scan the outputs of the thermostatically controlled shut-off valves and temperature sensors associated with each unit and operative to generate a plurality of signals, one for each circuit, each representative of the integral of the difference between the inlet and outlet temperatures for that circuit over the time period that the flow control valve for that circuit is open.
Claim 2
Independent Claim
162 words
A system for measuring the thermal energy dissipated in each of a plurality of units, each having a separate fluid circulating circuit served from a common pressurized main, comprising: thermostatically controlled electric shut-off valves disposed in each fluid circuit; an automatic constant flow regulating orifice in each fluid circuit; means for generating electrical signals representative of the inlet and outlet temperatures of the fluid medium in each circuit; and a digital computer connected to each of the shut-off valves and operative to receive the electric signals representative of the inlet and outlet fluid temperatures from each circuit, the computer being programmed to successively scan the outputs of the thermostatically controlled shut-off valves and temperature sensors associated with each unit and operative to generate a plurality of signals, one for each circuit, each representative of the integral of the difference between the inlet and outlet temperatures for that circuit over the time period that the flow control valve for that circuit is open.
Claim 3
Dependent Claim
19 words
The system of claim 1 wherein said automatic flow control orifices are of the pressure compensating variable orifice type.
Claim 4
Dependent Claim
28 words
The system of claim 1 wherein the thermostatic shut-off valve, automatic flow regulating valve, and of the temperature sensors in each unit are integrated in a single assembly.
Claim 5
Dependent Claim
16 words
The system of claim 1 wherein each unit comprises a separate unit in a multi-tenant building.
Claim 6
Dependent Claim
44 words
The system of claim 1 in which each of the units comprises one tenant occupied area of a multiple tenant building and each thermostatically controlled valve includes a temperature sensor disposed within its associated area and operative to sense the temperature within that area.
Claim 7
Dependent Claim
20 words
The system of claim 1 including an electronic memory for recording the signals representative of the integral for each circuit.
Claim 8
Dependent Claim
33 words
The system of claim 6 including display means connected to the computer and means for controlling the computer to cause the display of the recorded integral associated with any one of the units.
