摘要： An air conditioning apparatus comprises a switching valve for switching the flowing direction of a refrigerant discharged from a compressor to carry out either cooling operation, heating operation or defrosting operation; an outdoor heat exchanger for receiving the refrigerant supplied by the compressor through the switching valve to make the refrigerant heat exchange with air to be heat exchanged; an indoor heat exchanger for making the refrigerant heat exchange with a fluid to be heat exchanged; an oil separator which is arranged in a discharging side refrigerant pipe connecting the switching valve and the discharge port of the compressor to separate the refrigerant and a refrigerating machine oil which are discharged from the compressor; a first and second accumulators which are connected in series in an intake side refrigerant pipe connecting the switching valve and the intake port of the compressor; a first bypass passage for connecting the oil separator and the second accumulator through a solenoid valve; and a second bypass passage for connecting the oil separator and the intake port of the compressor through a metering device. As a result, the refrigeranting machine oil is returned to the compressor through the first bypass passage or the first and second bypass passages to prevent the compressor from failing due to shortage of the refrigeranting machine oil.

摘要： A heat pump having a plurality of compressors disposed in parallel is disclosed. An oil separator is disposed on the discharge sides of the compressors so as to separate any lubricating oil entrained in the refrigerant discharged from the compressors. The lubricating oil is accumulated in the oil separator and is then passed to an accumulator, from where it is returned to the compressors with returning refrigerant. Control means are provided for controlling the flow of oil from the oil separator into the accumulator. Rather than passing through the heat exchangers of the apparatus, the lubricating oil is quickly returned to the compressors from which it is discharged, thereby preventing oil shortages from developing in the compressors. Check valves are provided on the intake and discharge sides of the compressors to prevent liquids remaining in the piping of the apparatus from accumulating in the intake and discharge openings of a stopped compressor, thereby preventing damage to the valves of the compressors at start-up.
摘要翻译：公开了一种具有并联设置的多个压缩机的热泵。在压缩机的排出侧设置油分离器，以分离从压缩机排出的制冷剂中夹带的任何润滑油。润滑油积聚在油分离器中，然后通入蓄能器，从返回制冷剂返回到压缩机。提供控制装置用于控制从油分离器到储油器的油流。不是通过设备的热交换器，而是将润滑油快速地返回到压缩机排出的压缩机，从而防止压缩机中的油不足以形成。止回阀设置在压缩机的进气和排出侧，以防止装置的管道中残留的液体积聚在停止的压缩机的进排气口中，从而防止在启动时对压缩机的阀的损坏。

摘要： An air blower chamber includes a partition plate provided with an air intake opening, an air blower mounted on the partition plate so as to be detachable from the same through the air intake opening, a box for auxiliary parts and an air filter placed at an inlet opening of said main body. An air intake panel is detachably fitted to an opening of a ceiling which is spaced apart from and below the inlet opening and an air intake chamber for connecting the inlet opening to the opening of the ceiling. Accordingly, inspection and services for blades and the motor of a blower, auxiliary parts and air filter can be easily made by simply detaching the air intake panel without necessity of a worker to enter in the ceiling.

摘要： After a row address and a column address are supplied to a dynamic RAM in response to a row address strobe signal and a column address strobe signal, respectively, a high impedance state is maintained for column address access time period after the fall timing of the column address strobe signal, thereafter data is outputted to a data bus, and the high impedance state of the data bus is quickly resumed after the rise timing of the column address strobe signal. If different column addresses of RAM at the same row address are successively read, data are read and outputted to the data bus in response to a change only in the column address strobe signal, and thereafter, even after the high impedance state of the data bus is quickly resumed, a data value is held by the data bus until the dynamic RAM outputs the data.
摘要翻译：在行地址和列地址分别响应于行地址选通信号和列地址选通信号而被提供给动态RAM之后，在列的下降定时之后的列地址访问时间段中保持高阻抗状态地址选通信号，此后数据被输出到数据总线，数据总线的高阻抗状态在列地址选通信号的上升定时之后快速恢复。如果连续读取同一行地址的RAM的不同列地址，则只响应于列地址选通信号的变化而将数据读取并输出到数据总线，此后即使在数据总线的高阻抗状态快速恢复，数据总线保持数据值，直到动态RAM输出数据为止。
