摘要:
An automobile air-conditioner wherein a controlled variable used to determine the control mode of a component of the air-conditioner is corrected or restricted according to the amount of shifting of the head part setting temperature for driving the component of the air-conditioner based on the corrected or restricted controlled variable. With this arrangement, an occupant of the automobile senses an enhanced change of the air-conditioning operation when the head part setting temperature is changed.
摘要:
An automobile air-conditioner capable of controlling the displacement of a compressor in view of the traveling condition and air-conditioning condition of an automobile so as to maintain a pleasant feeling of the air-conditioning and an accelerating ability of the automobile in harmony with each other. The air-conditioner includes an air-conditioning preference judgment device by means of which a normal control of the air-conditioning operation is maintained when the judgment of this judgment means indicates the existence of an air-conditioning preference condition. The air-conditioning is performed in preference to acceleration of the automobile depending on the degree of acceleration of the automobile even when the automobile is accelerated.

摘要:
An apparatus for controlling an automotive air-conditioner wherein an air distribution to left and right sides of a vehicle passenger compartment is achieved either in an automatic control mode or in a manual control mode which is selected by a judgement made based on the vehicle passenger compartment and the quantity of solar radiation. In case of the automatic control mode, the rate of change of the air distribution control is changed dependent upon the position set by an air-distribution setting unit relative to the direction of solar radiation so as to meet the occupant desire.
摘要:
In an air conditioner including a variable-capacity compressor, a control system performs a PI calculation based on a temperature deviation between the actual temperature of the air downstream of an evaporator and its target temperature, thereby determining a control amount for controlling the capacity of the compressor. It is judged whether or not the sum of a proportional control component and an integral control component exceeds a limit value of the control amount corresponding to the maximum capacity of the compressor. If this judgment is in the affirmative, an ordinary integral calculation is stopped, and the integral control component is determined by subtracting the proportional control component from this limit value.
摘要:
An air conditioning control system for an automotive vehicle having an internal combustion engine. A variable capacity compressor has a pump having displacement thereof variable in response to a change in pressure within a controlled pressure chamber, a communication passage communicating between a low pressure chamber and the controlled pressure chamber, and a valve disposed to vary an opening area of the communication passage. An electromagnetic clutch connects and disconnects the compressor to and from the engine. An evaporator is connected to the compressor. A control unit controls the capacity of the compressor by supplying the valve with control current normally set within a predetermined range, to vary the opening area of the communication passage such that the temperature of outlet air from the evaporator becomes equal to a desired value. The control unit supplies the control current having a predetermined value larger than the above predetermined range over a predetermined time period to control the capacity of the compressor to the minimum value, when the electromagnetic clutch is brought into an engaged state from a disengaged state.
摘要:
An apparatus for controlling an automobile air-conditioner wherein the direction of solar radiation is determined based on a signal which is obtained by retarding the leading edge of a solar radiation signal and the position of an air-distributing door is controlled according to the thus obtained signal. A signal whose leading and trailing edges are progressively increasing and decreasing, respectively, is used for the calculation of a signal corresponding to the thermal load in the vehicle passenger compartment. The operation of various components of the air-conditioner including a blower is controlled by the result of calculation of the thermal load signal.

A document retrieval assistance method has a user interface with an interactive guidance function. In response to a search query, search results including a title list of retrieved documents is displayed alongside a separate display of topic words extracted from the retrieved documents which reflect the search results. In particular, a topic-word graph is displayed alongside a list of titles of the retrieved documents and the interface enables browsing of the documents using the topic words. Further, the interface permits emphasized display of the list of titles of the documents through direct selection of the titles displayed in the list or through selection of the topic words. Further, an associative search can be executed using a selected document to refine the original search results and develop updated displays of the search results and topic words contained in the documents.
摘要:
A receiver tank (2) formed into an airtight container having an inlet port (24) and an outlet port (25) for a refrigerant, wherein separates the refrigerant introduced in a gas-liquid mixture state is separated, and the separated liquid refrigerant is stored therein and discharged therefrom so to continuously supply it, and the airtight container is formed as a double tube of an inner tube (16) and an outer tube (17), which have their tops mutually communicated but their bottoms not; the inlet port is formed to communicate with the bottom portion of a passage formed between the two tubes; and the outlet port is formed at lower end portions of the inner and outer tubes to communicate with the interior of the inner tube. The structure of no communication between the outer tube and the inner tube was achieved by having a structure of fitting either of them with the other or by disposing a joint member. A structure for prevention of the inner tube from tilting is provided. And, airtightness is improved by forming a knurled portion on a contact portion of the members.
