摘要： Provided is a refrigeration apparatus that detects refrigerant leakage or refrigerant charge deficiency while restraining costs increasing. An air conditioning system (100) is equipped with a subcooling heat exchanger (16), a second outdoor expansion valve (15), a first refrigerant flow rate computing component (55), a second refrigerant flow rate computing component (56), and a refrigerant quantity determining component (57). The subcooling heat exchanger (16) includes a first flow path (161) disposed on a refrigerant primary circuit (RC1) and a second flow path (162) disposed on a bypass circuit (RC2). The second outdoor expansion valve (15) is disposed on an upstream side of the subcooling heat exchanger (16) in the bypass circuit (RC2). The first refrigerant flow rate computing component (55) calculates, as a first refrigerant flow rate (Fr1) on the basis of refrigeration cycle theory, the flow rate of the refrigerant flowing through the bypass circuit (RC2). The second refrigerant flow rate computing component (56) calculates, as a second refrigerant flow rate (Fr2) on the basis of fluid theory, the flow rate of the refrigerant flowing through the bypass circuit (RC2). The refrigerant quantity determining component (57) determines refrigerant leakage or refrigerant charge deficiency on the basis of a result of a comparison of the first refrigerant flow rate (Fr1) and the second refrigerant flow rate (Fr2).

摘要： A refrigeration system (20) includes a compressor (22), a gas cooler (24), an expansion device (26), and an evaporator (28). Refrigerant is circulated through the closed circuit system. Preferably, carbon dioxide is used as the refrigerant. As carbon dioxide has a low critical point, systems utilizing carbon dioxide as a refrigerant usually require the refrigeration system to run transcritical. When the system is operating inefficiently, the system is modified so the system operates efficiently. First, a parameter of the system is monitored by a sensor (70) and then compared to a stored value to determine if the system is operating inefficiently. If the system is operating inefficiently, the system is modified to an efficient system.

摘要： A cryosurgical catheter probe and method of operation are described. The probe comprises a Joule Thompson probe tip (20) joined to a catheter (10) which includes an inner supply conduit (12) and an outer exhaust conduit (14). A pump (26) is coupled to the downstream end of the exhaust conduit (14) to draw exhaust cryogen through the exhaust conduit. The pump (26) produces a negative pressure at the pump sufficiently great to produce a negative pressure in the exhaust path adjacent to the tip (20). The negative pressure reduces the chances of a leak, and also reduces the chances of cryogen escaping from the catheter into the patient's blood vessel if a leak does occur.
