摘要:
A vapor compression system includes a variable speed single stage compressor, a heat rejecting heat exchanger, an expansion device, and a heat accepting heat exchanger. The speed of the compressor is varied to control the refrigerant flow rate and match the cooling load requirements of the vapor compression system. A temperature sensor measures an air temperature in the refrigerated container. When the temperature sensor detects that the air temperature is above a threshold temperature, the microcontroller increases the speed of the compressor to increase the refrigerant flow rate and the cooling capacity of the vapor compression system. When the air temperature sensor detects that the air temperature is within a predetermined range from the set point temperature, the microcontroller sends a signal to slightly decrease the speed of the compressor, allowing fine adjustment of the cooling capacity of the vapor compression system to prevent overcooling of the refrigerated container.
摘要(中):
蒸气压缩系统包括变速单级压缩机,排热热交换器,膨胀装置和热接收热交换器。 改变压缩机的速度来控制制冷剂流量并匹配蒸气压缩系统的冷却负载要求。 温度传感器测量冷藏容器中的空气温度。 当温度传感器检测到空气温度高于阈值温度时,微控制器增加压缩机的速度,以提高制冷剂流量和蒸汽压缩系统的冷却能力。 当空气温度传感器检测到空气温度在设定点温度以上的预定范围内时,微控制器发出信号以稍微降低压缩机的速度,允许微调蒸汽压缩系统的冷却能力以防止过冷 的冷藏集装箱。
