摘要： PURPOSE:To automate switching of a dehumidifying time operation mode by controlling so that the operation mode can be switched between a dehumidifying mode and a cooling or heating mode according to data containing at least one of an outside air temperature and a target blowoff temperature. CONSTITUTION:Respective detecting signals of respective sensors 77 to 79 of an inside air temperature, an outside air temperature and solar radiation and a heat sensitivity setting unit 82 as a control target are read in an ECU 68 through an A/D converter 72. This ECU 68 controls the whole air-conditioning operation by practicing a prescribed control program, and controls so that an operation mode can be switched between respective modes of high temperature dehumidification, low temperature dehumidification, cooling and heating according to a switching condition on the basis of the outside air temperature and a target blowoff temperature when a front defroster switch is turned on. Thereby, opertability is improved, and the operation mode can be switched automatically in the proper timing, so that amenity can be maintained excellently.

摘要： PURPOSE:To prevent a decrease in a blown air temperature due to defrosting operation and to obtain comfortableness at the time of heating by inhibiting the defrosting of an outdoor heat exchanger during driving of a vehicle, and defrosting the exchanger while the charging circuit of a secondary cell is connected to an external charging power source after the driving of the vehicle is finished. CONSTITUTION:When an outdoor heat exchanger 58 is frosted during driving of a vehicle, the number of revolutions of a compressor 56 is increased to increase its refrigerant discharge capacity. When the driving of the vehicle is finished and the vehicle is frosted, a defrosting operation is executed when a charging circuit 93 of a secondary cell 92 is connected to an external charging power source. A four-way switching valve 57 assumes a position shown by solid lines during defrosting, a solenoid valve 63 is opened, high temperature gas refrigerant discharged from the outlet of the compressor 56 is supplied also to the exchanger 58 through a condenser 35 and the valve 63 to remove frost adhering to the surface of the exchanger 58 by heat radiation of the refrigerant.

摘要： PURPOSE:To make hot in a cabin in an efficient manner by using arefrigerating cycle and a hot-water heating system in combination. CONSTITUTION:A cooling heat exchanger 21 and a heating heat exchanger 22 of a heat pump type refrigerating cycle 4 are set up in a duct 2, while a heater core 33 of a hot-water heating system 5 is set up in the windward of this heating heat exchanger 22 (leeward from the cooling heat exchanger 21). This hot-water heating system 5 is used after stopping operation of the refrigerating cycle 4 at a time when the outside air temperature is low. When a temperature of hot water to lee fed to the heater core 33 is low, however, the refrigerating cycle 4 is used in combination, whereby desired heating capacity is secured. On the other hand, when the outside air temperature is not so low, operation of the hot-water heating system 5 is stopped and heating by means of operation of the refrigerating cycle 4 is carried out instead.

摘要： PURPOSE:To restrain the rise of the refrigerant discharge temperature of a refrigerant compressor and make small the capacity of a refrigerant container that stores a surplus refrigerant, in an air conditioner that conducts at least one of cooling and heating operations, and dehumidifying operation, by means of a freezing cycle. CONSTITUTION:At time of dehumidifying operation when an upstream heat exchanger 18 located upstream of a duct 2 functions as an evaporator and a downstream heat exchanger 19 located downstream of the duct 2 functions as a condenser, a refrigerant discharge temperature detected by means of a temperature sensor 39 surpasses 110 deg.C, then a controller 31 turns ON an exterior fan 26, and the refrigerant condensing ability of an exterior heat exchanger 21 is increased. Whereupon, a liquid refrigerant in the exterior heat exchanger 21 is decreased, and a liquid refrigerant is supplied into an accumulator 25, and as a result, the rise of the refrigerant discharge temperature of a refrigerant compressor 22 is restrained.

摘要： PURPOSE:To protect a frequency converter and to obtain an air conditioner for a vehicle which is capable of improving the durability of a compressor. CONSTITUTION:A compressor is driven by a compressor motor 23a and is provided with an inverter 37 between a power source 36, which also play a role of a wheel drive source and the compressor motor. A micro computer 40, when a pressure sensor detects that the voltage of the power source 36 comes off the predetermined permissible range, stops the output from the inverter 37 for an air conditioner to the compressor motor 23a. In addition, the micro computer 40, when the voltage sensor 43 detects that the voltage of the power source 36 enters the predetermined permissible range and the refrigerant pressure on the suction side and the refrigerant pressure on the discharge side of the compressor 23 are equal to each other after having stopped the output to the compressor motor 23a, restarts the output to the compressor motor 23a from the inverter 37 for the air conditioner.

摘要： PURPOSE:To improve efficiency in generating ozone by sucking the air cooled by a cooling unit, passing the sucked air dried by the cooling through an ozonizer to generate ozone and exhausting the air heated by a radiating unit. CONSTITUTION:Air is sucked from the outside through a cooling unit 15 of an electronic refrigerating unit 12, cooled and dehumidified. The dehumidified air is then introduced into an ozonization chamber 13, and a silent discharge is generated in an ozonizing mechanism 19 to generate ozone. The air having a high content of ozone is heated by the radiating unit 16 and discharged to the outside. The drain is revaporized by the radiating unit 16 to keep the steam content of the air in the ozonization chamber 13 and radiating unit 16 at a specified value. Consequently, ozonolysis is prevented, and the deodorizing and sterilizing effect of ozone is enhanced by the oxygen generated at this time.
