摘要： A system and method are provided to increase the horsepower of an induction motor. One technique for increasing the horsepower of a motor is to connect the motor to a variable speed drive that is providing an output voltage and frequency greater than the standard line voltage and frequency. The connection of the variable speed drive to the induction motor enables the motor to be operated in constant flux or constant volts/Hz mode and provide a greater output horsepower. Another technique for increasing the horsepower of a motor is to use a dual voltage motor configured for lower voltage operation and then provide the motor with the corresponding voltage and frequency for higher voltage operation. The higher voltage and higher frequency can be provided by a variable speed drive with or without voltage boost. A variable speed drive without voltage boost, but with frequency boost, can be used in situations where the standard main voltage is greater than the lower voltage rating.

摘要： A system and method are provided for variable speed operation of a screw compressor to obtain increased capacity and efficiency. The screw compressor is connected to an induction motor driven by a variable speed drive, wherein the screw compressor has a variable output capacity that is dependent on the output speed of the motor. To obtain increased capacity and efficiency, the screw compressor is operated at a speed greater than the screw compressor's rated speed and does not include a slide valve. The maximum operating speed of the screw compressor, which speed is greater than the rated speed, is related to the maximum operating speed of the motor when operated at a voltage and frequency provided by the variable speed drive that is greater than the motor's rated voltage and frequency in a constant flux or constant volts/Hz mode.

摘要： A control system for regulating operation of a heat pump includes a basic timer circuit which is utilized in different ways for different purposes. The system senses pressure across the outdoor coil, outdoor temperature, temperature in the liquid line to and from the outdoor coil, and temperature of the compressor discharge line. The control system initiates a defrost cycle for the outdoor coil responsive to a high static pressure across the outside coil, at the same time that the liquid line temperature is below a preset temperature. The defrost cycle is terminated when the liquid line temperature reaches a given temperature or when that liquid line temperature has been at a lower temperature for a certain time interval as determined by the basic timer circuit. When the compressor is shut down, the timer is also started to ensure that the compressor is not brought back on before the expiration of the basic shut-down time interval. In addition the compressor cannot be operated when the outside temperature is at or below whatever temperature is determined by the standby heat setting. The compressor likewise cannot be operated when there is a second call for defrost within a given time interval, or a high temperature in the compressor discharge line. The compressor cannot be restarted after a power failure until a preset time interval has elapsed.
摘要翻译：用于调节热泵操作的控制系统包括以不同方式用于不同目的的基本定时器电路。该系统感测室外线圈的压力，室外温度，到室外线圈的液体线路中的温度和压缩机排出管线的温度。响应于跨越外部线圈的高静态压力，控制系统启动室外线圈的除霜循环，同时液体管线温度低于预设温度。当液体管线温度达到给定温度时，或当液体管线温度处于较低温度下一定时间间隔时，除霜循环结束，由基本定时器电路确定。当压缩机关闭时，定时器也启动，以确保压缩机在基本关闭时间间隔到期之前不会重新启动。此外，当外部温度等于或低于由待机热定形确定的温度时，压缩机不能操作。当在给定的时间间隔内有第二次除霜或压缩机排放管线中的高温时，压缩机也不能操作。停电后，直到预设的时间间隔过后，才能重新启动压缩机。
