摘要： A variable capacity refrigeration system includes a control scheme having three interrelated closed loops. The system includes a refrigeration system controller and at least one variable speed, electronically commutated DC motor driving a compressor. In the first closed loop, the controller supplies a speed command signal to a motor drive which governs the speed of the motor driven compressor. The speed of the compressor varies the system's capacity to condition the temperature of a comfort zone. A temperature sensor in the zone provides a temperature feedback signal to the controller to complete the first closed loop. In the second closed loop, the speed command signal from the controller is varied in response to a speed feedback signal received from a compressor drive which includes both the motor and the motor drive. The third closed loop is between the motor drive and the motor. The motor drive electronically commutates the motor as it delivers an electrical supply to the motor in response to a position feedback signal generated from within the motor. The three loops are interrelated in that the output of the controller responds to feedback from both the temperature sensor and the compressor drive, and the output of the motor drive responds to input from both the motor and the controller.

摘要： A microcomputer based defrost control for a heat pump system that "learns" from previous defrost cycles to achieve optimum defrost control at each of a plurality of outdoor temperature ranges, even if the heat pump system operating parameters change due to system aging. At the conclusion of each defrost cycle, the control determines the differential temperature between the outdoor ambient air and the outdoor heat exchanger and compares that value to a value stored in microcomputer memory representing a previous best such post-defrost differential temperature for the same ambient air temperature range. The control then calculates a defrost differential temperature initiate value, corrected to compensate for any loss of defrost performance indicated by the current post-defrost cycle differential temperature. After a period of time during which a number of defrost cycles have occurred, the minimum post defrost differential temperature value for each ambient temperature range becomes the best performance measure of the defrost cycle for the heat pump system. The stored minimum values are reset to zero when the control and heat pump system are deenergized. When the system is again turned on, new optimum defrost initiate values are again determined over a period of time. In addition, various default conditions cause the control to initiate an extended defrost cycle. The control is programmed to alert the operator by lighting a lamp on the thermostat should such a fault condition occur.
摘要翻译：一种用于热泵系统的基于微机的除霜控制，其从先前的除霜循环中“学习”，以在多个室外温度范围内的每一个达到最佳除霜控制，即使由于系统老化而导致热泵系统运行参数改变。在每个除霜循环结束时，控制器确定室外环境空气和室外热交换器之间的温差，并将该值与存储在微型计算机存储器中的值表示相同的环境空气的先前最佳的后除霜差温温度范围。控制然后计算除霜差温启动值，校正以补偿由当前后除霜循环差温表示的除霜性能的任何损失。在发生多次除霜循环的一段时间后，每个环境温度范围的最小后除霜差温值成为热泵系统除霜循环的最佳性能指标。当控制和热泵系统断电时，存储的最小值将重置为零。当系统再次打开时，在一段时间内再次确定新的最佳除霜启动值。此外，各种默认条件导致控制启动扩展除霜循环。控制器被编程为通过点亮恒温器上的灯来警告操作者，如果发生这种故障状况。

摘要： An HVAC system includes a variable speed electric motor driven fan for circulating air to an enclosed space through an indoor unit for providing heating or cooling effect to air circulated through the indoor unit. A controller with user or system installer actuatable switches includes a programmable microcontroller providing a pulse width modulated (PWM) signal to a motor control unit to select a predetermined air flowrate less than full air flowrate during system startup and shutdown. User input parameters include selected percentages of full air flowrate to satisfy requirements for reduced noise level, lower humidity and for improved sensible heating of air being circulated, the latter being effective particularly for heat pump applications. Selection of pre-run, short run and shutdown cycles may be provided.

摘要： An air-handler includes an AC induction motor that drives a blower to move air across a heat exchanger. A switch system selectively determines whether the blower motor operates at its rated full speed or at a reduced speed. For full speed operation, the switch system couples an AC supply at a nominal line frequency directly to the blower motor and bypasses an inverter. For reduced speed operation, the switch system couples a lower frequency output of the inverter to the blower motor. The blower is operated at a reduced speed during a pre-run dehumidification mode, a post-run heat recovery mode, and/or an electronic air-cleaning mode. The switch system allows the rated current capacity of the inverter to be substantially less that the rated full load current of the blower motor.
