摘要： PURPOSE:To prevent an air filter and an opposing electrode from being brought into contact with each other and generating defective insulation without enlarging a set space in the depth direction by retaining a given space between an opposing electrode and an air filter by means of a filter guide provided on the opposing electrode. CONSTITUTION:Ionization lines 21 are disposed in tension on a main frame 12 and an opposing electrode 37 with electrode plates 38 facing the ionization lines 21 is provided. An air filter 46 is disposed facing said opposing electrode 37. A filter guide 42 for retaining these given facing intervals is provided on a surface facing the air filter 46 of opposing electrode 35. In order words, the air filter 46 and the opposing electrode 37 are prevented from being in contact with only by the thickness dimension of the filter guide 42, and electric insulation can be secured without increasing a set space in the depth direction.

摘要： PURPOSE:To make it possible to defrost during the heating operation, stabilize the operation, and simplify the refrigeration cycle by arranging the outdoor heat exchanger and a heat-absorptive section in a heat storage device in parallel during the heating operation. CONSTITUTION:A main circuit 27 is formed by connecting a capacity-variable compressor 21, a heat exchanger 22a for heating in a heat storage device 22, a four-way valve 23, an indoor heat exchanger 24, a pressure reducer 25, an outdoor heat exchanger 26, and the four-way valve 23 in sequence. A defroster circuit 30 connects the intervening part between the compressor 21 and the heat exchanger 22a for heating to the inlet of the outdoor heat exchanger 26 with a two-way valve 28, a pressure-reducer 29, and a heat-absorptive heat exchanger 22b in the heat storage device 22 intervening therebetween. Thus the indoor heat exchanger 24 and the heat-absorptive heat exchanger 23b are arranged in parallel. The amount of the heat released to the indoor heat exchanger 24 and that of the heat released to the outdoor heat exchanger 26 for defrosting are decided by the ratio of the quantity of the refrigerant flowing to the indoor heat exchanger 24 to that of the refrigerant to the heat-absorptive heat exchanger 22b. Therefore, by adjusting the throttle resistance of the pressure reducer 29, it is made easy to adequately control the heating capacity and the defrosting capacity.

摘要： PURPOSE:To prevent drop-wise water condensation which will pollute carpets, etc. in a room on the surface of a front face panel during air conditioning by providing the front face panel of an indoor air conditioner unit with a coolant passage and passing a coolant through the coolant passage when operating room heating and not passing the coolant through it when air cooling. CONSTITUTION:During room heating operation a coolant flows through a four- way valve 5, coolant passage 13, check valve 16, and indoor heat exchanger 8 in this order, and the coolant passage 13 acts as a condenser like an indoor side heat exchanger 8, so that affront face panel 1 of an indoor air conditioner unit in which the coolant passage 13 is incorporated becomes a radiation panel by heating. On the other hand, during air cooling operation, the coolant flows through the indoor heat exchanger 8, a check valve, and the four-way valve 5 in this order, so that the coolant does not flow in the coolant passage 13 but only through the indoor side heat exchanger 8. Accordingly the front panel 1 is not heated and no water drops condense on the front panel 1.

摘要： PURPOSE:To enable a radiation part to be cooled by a method wherein a heating part of an invertor device is arranged in the midway of a line communicating an outer part with the interior of a fan casing and the outer air is flowed into the fan casing through the air passage. CONSTITUTION:When an air conditioner is started to operate, a lateral flow fan is rotated and surrounding atmosphere is sucked through a surrounding atmosphere suction port 15 and at the same time since the position of the fan casing opening 9 is located at the suction side of the lateral flow fan, the air is sucked from this opening 9 (Arrow A). Due to this fact, an inner pressure at the fan motor storing part (b) is decreased and the air at the storing part (c) is sucked from the invertor opening 8 arranged at the partition plate 7-2. Then, the surrounding atmosphere at the storing part (c) is sucked through the opening hole 10 (arrow C) passed through the heat sink 6, (arrow B) and flowed toward the invertor opening 8. Under operation of the lateral flow fan 2, the heat sink 6 is forcedly cooled.

摘要： PURPOSE:To control ON and OFF motion of a compressor and to improve energy efficiency throughout the year, by a method wherein, in case the operating frequency of the compressor is minimum during heating operation, an outdoor fan is brought to a low speed operating state or a stop. CONSTITUTION:During heating operation, a control device 10 decreases the number of revolutions of a compressor 1 in proportion to an increase in temperature Ta detected by an inadoor temperature sensor 9, and when temperature is decreased to about a set value Ta, the compressor 1 is operated at lowermost frequency (minimum capacity). When, for example, temperature Te, detected by an outdoor temperature sensor 8, is increased to higher than a previously set temperature T1 an outdoor fan 11 is brought to a lower speed rotating state or a stop. When the outdoor fan 11 is brought to a stop, the evaporating temperature of a heat exchanger 1 on the indoor side is decreased, and as a result, a heating capacity and an input are decreased. If a chamber temperature is decreased to a set value during said decrease, operation is brought to a stop, and if the chamber temperature is not decreased to the set value, operation is continued in a condition in that the outdoor fan is brought to a stop. In which case, in case the temperature of the heat exchanger on the outdoor side is increased in succession to higher than the set value T1 for a specified time t2 the outdoor fan 11 is driven.
摘要翻译：目的：为了控制压缩机的开启和关闭运动，并提高全年的能源效率，通过一种方法，其中在加热操作期间压缩机的运行频率最小的情况下，室外风扇进入低速运行状态或停止。构成：在加热运转时，控制装置10与由室内温度传感器9检测到的温度Ta的升高成比例地减小压缩机1的转数，当温度降低到设定值Ta时，压缩机1 以最低频率（最小容量）运行。当例如由室外温度传感器8检测到的温度Te被提高到高于预先设定的温度T1时，室外风扇11进入较低速度的旋转状态或停止。当室外风扇11停止时，室内的热交换器1的蒸发温度降低，结果，加热能力和输入减少。如果在所述减少期间腔室温度降低到设定值，则操作停止，并且如果腔室温度不降低到设定值，则在使室外风扇停止的状态下继续操作。在这种情况下，在室外侧的热交换器的温度在规定时间t2内连续地高于设定值T1的情况下，驱动室外风扇11。

摘要： PURPOSE:To carry out a comfortable air-conditioning and an produce energy- saving effect by ensuring a stable and appropriate dehumidifying capacity at the time of dry operation at all times. CONSTITUTION:During dry operation, an outdoor fan 8 is controlled in the number N of revolutions in response to the temperature detected by a room temperature sensor 22 so that cold feeling dry, temperature-maintaining dry and warm feeling dry, in which dry air is different in temperature from one another, are selectively executed. At the time of cold feeling dry and temperature-maintaining dry, the opening degree of PMV 6 is controlled so that the refrigerant superheating degree is made constant in an indoor heat exchanger 7 which functions as an evaporator. At the time of warm feeling dry, the opening degree of PMV 6 is maintained constant.
