摘要： PURPOSE: To improve the wear resistance of the bearing of a compressor by using a molding of a sintered material in forming said bearing, embedding a metallic material which melts when calcined and forms a fluid passage in the bearing into said molding and sealing the sintered material with the molten metal.
CONSTITUTION: A main bearing 6 and an auxiliary bearing 7 are formed of a monolithic molding of a sintered material, in a hermetic type compressor provided with an electric motor 2 housed in the upper part in a hermetic casing 1 which can be divided to upper and lower parts and a compressor 5 coupled directly to the motor 2. An annular fluid passage 14 formed in the bearing 7 is formed in the following way: A metallic tubular body or bar-like body 15 formed of a metallic material which melts when calcined is preliminarily embedded into a monolithic molding 7 formed of a sintered material and the body 15 is melted in the stage of calcination to form the passage 14 with the space made after the melting. The sintered material is sealed by the molten metal and at the same time the wear resistance of the bearing 7 is improved by the same. A through- hole for the discharge valve 12 of the bearing 6 is similarly formed of a tubular body 15.

摘要： PROBLEM TO BE SOLVED: To improve performance without changing the sectional area of a heat transfer pipe or the number of passes, in the heat exchanger of an air conditioner using a refrigerant having a saturation pressure of 2500kPa or over at 50 deg.C. SOLUTION: The indoor heat exchanger 5 which constitutes the freezing cycle of an air conditioner has heat transfer pipes 21-24 where refrigerant flows and a large number of plate-shaped fins 20a-20c. Inside all or part of the heat transfer pipes 21-24, heat transfer accelerating members (spacers S1) having the so-called 'twist tape' form are inserted. The heat transfer on the refrigerant side (inside of the pipe) of the heat transfer pipes 21-24 at large is accelerated by causing the forced secondary flow (radial flow) in the refrigerant mainly within the heat transfer pipes 21-24 by the heat transfer accelerating member S1.

摘要： PURPOSE:To permit the arrival of an indoor humidity at a set humidity promptly by a method wherein the execution of drying operation or cooling operation is selected based on a temperature and a humidity in a room while the operating frequency of a compressor and the number of rotations of an indoor fan are set in accordance with a predetermined condition upon the drying operation. CONSTITUTION:When an automatic mode is set by a remote controller 21 and the detecting value of an indoor temperature sensor 22 is within a predetermined range about the set temperature, for example, the execution of drying operation is selected considering the detecting value of an indoor humidity sensor 23 and the operation mode of a control unit 20. In this case, the operation of a compressor 1, non-operation of a four-way valve 2, full opening of a PMV 4, choking of a PMV 6, the operation of an outdoor fan 8 and the operation of an indoor fan 6 are set respectively As a result, refrigerant is conducted as shown by solid line arrow signs in a diagram to form a dry cycle whereby an outdoor heat exchanger 3 is operated as a condenser and a first indoor heat exchanger 5 is operated as another condenser (reheater) while a second indoor heat exchanger 7 is operated as an evaporator respectively. According to this method, an indoor humidity is arrived at a set humidity promptly and surely.

摘要： PURPOSE:To perform an optimum and rapid temperature and humidity control in consideration of various loading conditions by setting an operating frequency of a compressor and a number of revolution of an outdoor fan through a fuzzy computation, of which an antecedent comprises a temperature deviation, a variation of the temperature deviation, a humidity deviation and a variation of the humidity deviation. CONSTITUTION:An outdoor heat exchanger 3 is connected to a discharge port of a compressor 1 through a four-way valve 2, and is connected to a first indoor heat exchanger 5 through an electronic expansion valve 4. Furthermore, the outdoor heat exchanger 3 is connected to a second heat exchanger 7 through an electronic expansion valve 6 and is connected to a suction port of the compressor 1 through the four-way valve 2. During a dry-mode operation, a deviation T between a room temperature Ta and a set temperature Ts, a variation DELTAT of the deviation T, a deviation H between a room humidity Ha and a set humidity Hs, and a variation DELTAH of the deviation H, respectively, are detected, and a control input DELTAF for an operating frequency F of the compressor and a control input DELTAN for a number of revolution of an outdoor fan are found by a fuzzy computation, of which an antecedent comprises the deviation T, the variation DELTAT, the deviation H and the variation DELTAH.

摘要： PURPOSE:To obtain a radiant-heat temperature sensor which keeps directional sensitivity excellently and detects radiant heat energy accurately by making it hard to incur the thermal effect from the outside, and blocking the effect of external air current. CONSTITUTION:A pair of reflecting mirrors 2a and 2b are juxtaposed so as to collect radiant heat energy from wall surfaces, floor surfaces and the like in the mutually neighboring directions. Temperature sensors 8a and 8b, which receive the radiant heat energy reflected from the reflecting mirrors and detect the temperature, are arranged at the position of the focal points of the respective reflecting mirrors. The front-surface sides of the temperature sensors and the reflecting mirrors are covered with an infrared-ray transmitting film 9 so as to transmit infrared rays. The temperature sensors are held in the same space. The effect of heat on the temperature sensors from the outside is made uniform, and the effect of external air current is blocked.
