US Patent:

40903729, May 23, 1978

Filed:

Mar 21, 1977

Appl. No.:

5/779735

Inventors:

Jeffrey Wayne Lamb - Jamaica Estates NY

International Classification:

F25B 1500

US Classification:

62141

Abstract:

Control system capable of controlling the refrigeration capacity of a refrigeration system adapted for cooling a fluid medium, the refrigeration system being of the type including a refrigerant; an absorbent having an affinity for the refrigerant; an evaporator for bringing the refrigerant into heat transfer relationship with the fluid medium, the evaporator having an inlet for receiving the fluid medium to be cooled in an outlet for discharging cooled fluid medium; an absorber in communication with the evaporator for removing refrigerant vapor therefrom; means for supplying a concentrated absorbent-refrigerant solution to the absorber; means for cooling the absorber to maintain the pressure therein below the pressure in the evaporator whereby refrigerant vapor migrates to the absorber to combine with the concentrated solution to produce a dilute solution; a concentrator for removing a portion of the refrigerant from the dilute solution for recirculation to the evaporator and for providing the concentrated solution; means for supplying the dilute solution to the concentrator; and means for controlling the concentration of the concentrated solution supplied to the absorber for controlling the refrigeration capacity of the refrigeration system. Control system includes means disposed for sensing the variations in temperature at the evaporator inlet and outlet and within the absorber for providing first, second and third tracking signal outputs indicative of the sensed temperature variations, the first tracking signal output being indicative of the variations in temperature of the fluid at the evaporator inlet, the second tracking signal output being indicative of the variations in temperature of the fluid at the evaporator outlet and the third tracking signal output being indicative of the variations in temperature in the absorber.

Appl. No.:

5/908109

Inventors:

Jeffrey W. Lamb - Jamaica Estates NY

International Classification:

F25B 1500

US Classification:

62141

Abstract:

A controller for regulating the energy consumption of a closed, variable capacity heating or refrigeration system comprises means for sensing at least two parameters, each indicative of the most energy efficient system capacity based on the parameter sensed, means for selecting the signal indicative of the most energy efficient system capacity and for providing an output signal indicative thereof, and means for comparing the output signal from the selecting means with the actual capacity of the system and for generating a signal indicative of the change in capacity necessary to adjust the actual system capacity to the most energy efficient capacity.

Filed:

May 8, 1980

Appl. No.:

6/148059

Inventors:

Doron Shafrir - Spring Valley NY
Jeffrey Lamb - Jamaica Estates NY

International Classification:

F25B 2900
F23N 520

US Classification:

165 12

Abstract:

A controller (10) for air conditioning units, heating units, and the like is disclosed. The controller (10) regulates the activation and deactivation of an energy consuming component of the unit, such as a compressor (12) or heating coil (14). The controller (10) includes a switch means (42, 66) operatively connected to the component and its energy source, the switch means (42, 66) being operable in a first mode wherein it interrupts the connection between the energy source and the component, a second mode wherein the connection between the energy source and the component is uninterrupted by the switch means (42, 66). The controller also includes control means (20, 54) operatively connected to the switch means (42, 66) for (a) operating the switch means (42, 66) in one mode when the space temperature exceeds a first predetermined temperature, (b) operating the switch means (42, 66) in the other mode when the space temperature is less than a second predetermined temperature and (c) cycling the switch means (42, 66) between its first and second modes according to a predetermined duty cycle when the space temperature is between the first and second predetermined temperatures.
