Abstract
Official abstract text for this publication.
A crankcase heating control system for a heat pump system includes a data receiving module and a power control module. The data receiving module receives data indicative of a temperature of a compressor of the heat pump system, data indicative of an ambient temperature, and data indicative of a current date and a current time. The power control module selectively applies power to a heater of a crankcase of the compressor and selectively disables the heater based on the temperature of the compressor, the ambient temperature, the current date, and the current time.
First claim
Opening claim text (preview).
What is claimed is: 1. A crankcase heating control system for a heat pump system, the crankcase heating control system comprising: a data receiving module that receives data indicative of a temperature of a compressor of the heat pump system, data indicative of an ambient temperature, and data indicative of a current date and a current time; a power control module that selectively applies power to a heater of a crankcase of the compressor and that selectively disables the heater based on the temperature of the compressor, the ambient temperature, the current date, and the current time; and a difference module that sets a temperature difference equal to the temperature of the compressor minus the ambient temperature, wherein the power control module disables the heater of the crankcase when the temperature difference is greater than a predetermined temperature. 2. The crankcase heating control system of claim 1 wherein the power control module applies power to the heater of the crankcase when the temperature difference is less than a second predetermined temperature that is less than the predetermined temperature. 3. A crankcase heating control method for a heat pump system, the crankcase heating control method comprising: receiving data indicative of a temperature of a compressor of the heat pump system; receiving data indicative of an ambient temperature; receiving data indicative of a current date and a current time; selectively applying power to a heater of a crankcase of the compressor; selectively disabling the heater based on the temperature of the compressor, the ambient temperature, the current date, and the current time; setting a temperature difference equal to the temperature of the compressor minus the ambient temperature; and disabling the heater of the crankcase when the temperature difference is greater than a predetermined temperature. 4. The crankcase heating control method of claim 3 further comprising applying power to the heater of the crankcase when the temperature difference is less than a second predetermined temperature that is less than the predetermined temperature.
