PROBLEM TO BE SOLVED: To prevent clogging of a capillary tube even when a diameter of the capillary tube is small in a refrigerating cycle wherein a gaseous refrigerant such as a CO 2 refrigerant is air-cooled by a radiator while its state changes in a supercritical area. SOLUTION: The refrigerator 1 is provided with a refrigerating cycle wherein the refrigerant from a compressor 11 sequentially circulates the radiator 13, expansion parts 21, 31, 41 and 42, and evaporators 6 and 7 and returns to the compressor, and an interior is cooled by the evaporators. When an outside air temperature is high, the gaseous refrigerant compressed by the compressor and having become a high temperature/high pressure is air-cooled by the radiator while its state changes in the supercritical area. At least one part of the expansion parts is composed of the capillary tube, and molecular sheaves 51 and 56 of a cylindrical dehydrator 14 provided in the refrigerating cycle are formed as a single block in a radial cross section of the dehydrator.

PROBLEM TO BE SOLVED: To quickly remove clogging of a capillary tube. SOLUTION: A heater 20 is provided in proximity to or in contact with the capillary tube 14. Temperature sensors 21 and 22 detecting the temperature of a refrigerant are provided respectively on the inlet side and outlet side of an evaporator 15. When clogging occurs in the capillary tube 14, the amount of flow of the refrigerant to the evaporator 15 side decreases and consequently the degree of superheat, i.e., the temperature difference between the inlet and the outlet of the evaporator 15, becomes large. In the course of operation of a refrigerating circuit 10, the temperatures on the inlet side and the outlet side of the evaporator 15 are detected and the difference between them is computed. When this temperature difference is a prescribed value or above, the capillary tube 14 is regarded as clogged and the heater 20 is made to heat by a signal from a heater drive control part 23 so as to heat the capillary tube 14. Thereby a dissolved substance being deposited is re-dissolved in the refrigerant or the like and made to flow to the evaporator 15 side together with the refrigerant, thus clogging being removed.

PROBLEM TO BE SOLVED: To provide a method and a device for maintaining a normal refrigerating cycle by avoiding generation of dry snow in an expansion valve while using a low evaporation temperature, and preventing clogging of the expansion valve when using carbon dioxide, or mixed gas of carbon dioxide as a coolant. SOLUTION: In the refrigerating cycle, carbon dioxide, or its mixed gas is used as a coolant. A bypass pipe from a hot gas pipe carrying hot gas discharged from a refrigerator (compressor) is connected to a coolant inflow side of the expansion valve arranged in a primary side of a cooler (evaporator). When a low pressure is detected by a pressure detecting switch, a solenoid valve of the bypass pipe is opened, hot gas is sent into the expansion valve, and the dry snow in the expansion valve is melted.

HVACのエアフィルタが目詰まりを起こしたことを示すために、蒸発器のバイパス係数が使用される。 バイパス係数は、蒸発器と直接に接触せずに迂回する空気の量を表す。 エアフィルタの目が詰まると、バイパス係数は低下する。 バイパス係数はさらに、エアフィルタの目詰まりの早期検出のために使用することもできる。 温度測定値を使用することによって第1のバイパス係数が計算され、空気の流量を使用することによって第2のバイパス係数が計算される。 これらの2つのバイパス係数の差が誤差を決定する。 この誤差の増大は、エアフィルタが目詰まりを起こしたことを示す。 エアフィルタが目詰まりを起こしたかどうかを検出するために、蒸発器の成績係数を計算することもできる。 この成績係数の低下は、エアフィルタが目詰まりを起こしたことを示す。
