Disclosed is an air conditioner and, in particular, an air conditioner which is capable of blowing out warm air in heating mode. In the air conditioner of this invention, the condenser is thermally separated into an air-upstream-side and an air-downstream-side heat exchanger, and the heat exchange capacity of the air-downstream-side heat exchanger is adjusted, so that, under preset operating conditions, the entire refrigerant in the air-downstream-side heat exchanger can be kept in the superheated-gas phase, thus making it possible to blow out warm air having a temperature higher than the condensation temperature. Further, the refrigerant temperature at the outlet of the air-downstream-side heat exchanger is measured by a temperature sensor, and the revolving speed of the compressor, the revolving speed of the fan, etc., is so controlled that the temperature measured is kept at a level higher than the condensation temperature. Thus, under all operating conditions, the entire refrigerant in the air-downstream-side heat exchanger can be kept in the superheated gas phase, thereby making it possible to blow out warm air having a temperature higher than the condensation temperature.

A control system for a compressor motor used with an air conditioning unit is disclosed. A current for generating a non-rotating magnetic field is supplied to the compressor motor to preheat a compressor. A current for generating a rotating magnetic field is also supplied to the compressor motor together with the current for generating a non-rotating magnetic field to heat the compressor. The heat pump using this control system is thus capable of transmitting sufficient heat energy immediately after start of the operation of the heat pump.

A reagent feeder which can to be used in both a finger-push system and a slide system by only attaching and detaching a simple auxiliary component to and from a case body depending on the state of operation or a preference of the operator. The feeder includes a case body, a sphere discharge port and a discharge device, so as to discharge a sphere one by one by pushing down the discharge device. The discharge device is provided with an operation lever which extends out of the case body and can be pushed down by a finger. A slide cover surrounding an outer periphery of the case body is attached to the case body in such a way that it can be moved freely in a vertical direction and can be detached from the case body. The slide cover is engaged with the operation lever of the discharge device so that it can be moved integrally with the discharge device.

A radiation-shielded injector comprises a cylinder of radiation shielding material having a cutout, a transparent radiation shielding plate being fitted to the cutout, a through-hole being provided at the closed end of the cylinder, a winged finger holding member being fixed to the cylinder, a cap having a hole for the passage through of a plunger being detachably attached, and a syringe-type body encapsulated with radioactive material, the cap being attached to the free end of the cylinder whereby the body is fixedly caught between the closed end of the cylinder and the cap. The infected is characterized by forming a built-up portion like a bank of radiation shielding material on the cutout periphery of the cylinder, the peripheral lateral side of the transparent plate being thereby covered with the thickness of the built-up portion. The radiation-shielded injector thus designed can minimize leakage of radiation and effectively protect the operator from radiation exposure.

In switching by failure, no switching is performed when a packet of IP packet is lost or a packet has not arrived even when a predetermined time has elapsed, which are not recognized as a failure. There is provided a duplicate transmission path switching device for data packets having the same information configuration to a main transmission path and an auxiliary transmission path. The device includes a transmission failure monitoring unit for monitoring a transmission failure of the main transmission path; a switching receiving unit arranged at the downstream of the transmission failure monitoring unit capable of receiving a packet from the main transmission path during a normal mode, and switching to the auxiliary transmission path to acquire a packet from the auxiliary transmission path in a predetermined mode; and a switching command output unit used when the monitoring result shows that a transmission failure is present, for outputting a switching command capable of switching to the auxiliary transmission path before the transmission failure reaches the switching/receiving unit, to the switching/receiving unit.

In an appliance controller 100 for controlling a household electric appliance, a unit information holding part 131 holds unit information identifies a household electric appliance 10, and an operation restriction information holding part 133 can hold operation restriction information indicates operation restrictions to be imposed on the household electric appliance 10. A receiving part 120 receives a forcible control signal transmitted by wireless and demodulates unit information and operation restriction information. A decision part 132 causes the operation restriction information holding part 133 to hold the received operation restriction information when the unit information held in the operation restriction information holding part 133 matches the received unit information. An appliance control part 210 (control computer) controls the operation of the household electric appliance 10 according to the operation restriction information held in the operation restriction information holding part 133.

In a refrigerant cycle apparatus, an energy-saving operation is performed by using a refrigerant which is used in a supercritical state. A refrigeration cycle apparatus is constituted by a main compressor, an expander, a sub compressor independently placed in an upstream side of the main compressor, a use side heat exchanger, a heat source side heat exchanger and the like. A refrigerant such as a carbon dioxide or the like which is used in a supercritical state is employed as the refrigerant. The sub compressor is driven by utilizing a recovered energy by the expanding device. Further, a refrigerant tank is provided, and properly controls an amount of the refrigerant circulating in the refrigerant cycle.
摘要:
The present invention relates to air conditioning systems and more particularly to an air conditioning system which provides air conditioning in each of a plurality of spaces. The air conditioning system according to the present invention divides a space with partitions into a plurality of air conditioning spaces and controls the temperature by cooling and heating mediums supplied from an external heat source using a three-way valve and an expansion valve. The air conditioning system includes an ID card for identifying a person which uses the air conditioning system. If a person is present to use the air conditioning system, the set or measured values of the environmental conditions for that person is stored. When that person again uses the air conditioning system, the system calculates the environmental conditions stored by the person in accordance with his stored set or measured environmental condition values. Each of the individuals' preferred comfortable environments is automatically realized by calculating the set values for that person in accordance with his current or past set conditions independent of the space. Changes to his preference to the environmental conditions are easily made.
