Claims

[Claims for Utility Model Registration] 1. The compressor 1 includes a heat source side heat exchanger 7, a pressure reducing mechanism 8,
A refrigerant circulation circuit is constructed by sequentially connecting the heat exchangers 10 on the user side, and a fan 12 is attached to the heat exchanger 10 on the user side, and the operation of the fan 12 causes the heat exchanger 10 on the user side to be activated. Air temperature detection means 13 is installed on the air circulation path before the passing air passes through.
furthermore, the air temperature detection means 1 during operation is provided.
When the detected temperature at step 3 passes through the thermo-on point and exceeds the thermo-off point, the refrigerant is circulated and the fan 12 is stopped, and when the detected temperature during the stoppage passes through the thermo-off point and exceeds the thermo-on point, the refrigerant is circulated. The refrigeration system includes an operation control means 22 for restarting the fan 12, and a clock means 31 for measuring the stop time from the time when the fan 12 is stopped beyond the thermo-off point, and a timer means 31 for measuring the stop time from when the fan 12 is stopped beyond the thermo-off point, When the detected temperature is between the thermo-off point and thermo-on point at the time when the operation control means 2
2, a first stop start means 32 for outputting an operation request signal to the first stop fan control means 33 for operating the fan 12 for a specific period of time when the detected temperature is on the opposite thermo-on point side from the thermo-off point; When the detected temperature after a specific period of time is closer to the thermo-on point than the thermo-off point, the operation control means 2
2. A refrigeration system characterized in that a second stop start means 34 is provided for outputting an operation request signal. 2. A fan stop means 35 is provided to maintain the fan 12 in a stopped state until the operation is restarted by the operation control means 22 when the detected temperature after the specified time has elapsed is not at the thermo-on point side. A refrigeration system according to claim 1, characterized in that:
