초록 ▼

A method and device for controlling the operation of a heat pump having a primary heat system and an auxiliary heat system, and used to heat air circulating in an enclosure such as a building, the invention comprising a first sensor positioned in the return duct of the heating system for measuring the temperature of air being returned to the heat system from the enclosure, a second sensor for measuring the temperature of air which has been heated only by the primary heat system, a temperature comparing relay for comparing the two sensed temperatures and determining the difference between them and actuating the auxiliary heat system only when the temperature difference is less than a predetermined set point, for example 4.degree. F., thereby providing a significantly enhanced operating efficiency of the heating system.

대표청구항 ▼

[ I claim:] [1.] A heat pump control system for controlling the operation of auxiliary heating elements associated with a heat pump primary heating system comprising first and second temperature sensor for measuring the temperature of return air entering into the heating system and air heated only by the primary heating system, means for determining the difference between the temperatures sensed by said first and second temperature sensors, comparing said difference with a predetermined set point, and operating said auxiliary heating elements when said difference is below said predetermined set point.
