Abstract
PURPOSE: To heighten the reliability and prevent abnormal noises, by installing thermosensitive cylinders between communication pipes extending from thermosensitive expansion valves to evaporators and gas pipes extending from the outlet ports of the evaporators.
CONSTITUTION: Parts of the communication pipes 10A, 10B extending to the evaporators 3A, 3B from the outlet ports of the thermosensitive expansion valves 4A, 4B installed in liquid pipes 5A, 5B branched from a main liquid pipe 5 are located near parts of the gas pipes 6A, 6B extendng from the outlet ports of the evaporators 3A, 3B to a main gas pipe 6 of an outdoor unit. The thermosensitive cylinders 7A, 7B are provided between the nearby parts. Electric heaters 8A, 8B are placed near the cylinders. When the electric heaters are energized, the surface temperature of each heater becomes equal to a predetermined overheat temperature of the outlet pipes of the evaporators 3A, 3B. The thermosensitive cylinders 7A, 7B detect the degree of overheat of gas at the outlet ports of the evaporators 3A, 3B pansion valves 4A, 4B. When cooling is stopped, the thermosensitive cylinders 7A, 7B are affected by the coolant liquid in the communication pipes 10A, 10B to open the thermosensitive expansion valves 4A, 4B with a high responding property
