Optimizer for single staged refrigeration systems
First Claim
8-1. The method of claim 1, wherein determining the output of said speed modulation device further comprises solving a speed modulation equation comprising the steps of:
- modulating said compressor at minimum speed in heating mode;
recording an average of said supply air temperature values at a first halftime and an average of said supply air temperature values at a second half time;
inputting said supply air temperature values at said first half time and said second half time into said speed modulation equation.

Abstract
An optimizer for a single staged refrigeration system comprising a speed modulation device, controller, and supply air temperature sensor. The optimizer is intended for modulating the speed of the indoor fan and compressor in existing or new refrigeration systems in settings including but not limited to residential houses/buildings, residential heat pump systems, commercial heat pumps systems, water source heat pumps, and roof top units. The optimizer solves humidity and noise problems in existing systems, reduces peak demand, increases energy efficiency, reduces energy consumption rates, and minimizes compressor failure rates and O&M costs.

9. An optimizer for modulating the speed of a fan and compressor for a single staged refrigeration system using an existing power source, said optimizer comprising;
-
a speed modulation device in proximity to said existing power source and linked with said indoor fan and compressor, said speed modulation device configured to collect power and current values from said existing power source and convert said existing power source to a frequency for powering said fan and compressor at a predetermined speed; a supply air temperature measuring device linked with said fan and operable to measure supply air temperature values; a control system in signal communication with said speed modulation device and supply air temperature measuring device, said control system configured to send power commands to and receive said power and current values from said speed modulation device and said supply air temperature values from said supply air temperature measuring device and, based on said power and current values determine the activity status of said indoor fan and compressor, and based on said supply air temperature values and power values determine the system mode of said indoor fan and compressor. - View Dependent Claims (10, 11, 12, 13, 15, 16, 17, 18, 19, 20)
