摘要： PURPOSE:To enable both cooling operation and defrosting operation during an intermediate period and winter season to be performed and to restrict hot air blowing during defrosting operation as much as possible by a method wherein a freezing cycle performs a defrosting operation in a reverse cycle when a defrosting instruction is outputted to one freezing cycle under condition in which both freezing cycles perform a cooling operation and simultaneously indoor blower and outdoor blower are stopped one by one. CONSTITUTION:As a cooling and heating operation changing-over switch 18 is connected to a cooling side and each of contact points for de-icers 16 and 17 is connected to four-way valve changing-over coils 12 and 13, two freezing cycles may perform a cooling operation. For example, when the de-icer 16 outputs a defrosting instruction, the contact point of the de-icer 16 is changed over and connected to an auxiliary relay 10 to energize the four-way changing-over coil 12, resulting in that the freezing cycle may start the defrosting operation in its reverse cycle. Simultaneously with this defrosting operation, the auxiliary relay 10 is energized to cause its b-contact point 22 to be opened, so that an electromagnetic contact 3 for the indoor blower and an electromagnetic contact 5 for the outdoor blower are deenergized. That is, one of the indoor and outdoor blowers is stopped.

摘要： PURPOSE:To eliminate a conversion mode and reduce a cost of air conditioner by a method wherein an indoor blower and an outdoor blower are composed of two blowers, respectively, and then one freezing cycle is changed over from a heating operation to a defrosting operation and simultaneously with this changing-over operation, one indoor blower and one outdoor blower are stopped to enable amount of air to be adjusted. CONSTITUTION:During a first freezing cycle and a second freezing cycle for use in heating operation, when a de-icer 17, for example, outputs a defrosting instruction, a contact point is changed over and connected to an auxiliary relay 12, resulting in that a four-way valve changing-over coil 19 is deenergized, a four-way valve 4 is changed over and then the first freezing cycle may start a defrosting operation. Simultaneously with this defrosting operation, the auxiliary relay 22 is energized, its b-contact point 22 is opened to cause a magnet switch 12A to be deenergized and then a blower 9A of an indoor blower device 9. Since the b-contact point at the outdoor blower 10A is opened by energization of the auxiliary relay 21, the outdoor blower 10A may also be stopped simultaneously with the indoor blower 9A.

摘要： PURPOSE:To easily design a wiring pattern in a short time by automatically erasing a part for a length less than a threshold value when the end side of an existent wire divided at the end point is not connected with any terminal for wiring or the other wiring path and the length to the end is less than the threshold value. CONSTITUTION:When wiring 4 is added to existent wiring 5, out of the divided lines of the wiring 5 to be partitioned at a connection end point 2 of the wiring 4, the divided line, for which nothing is connected t the other end side and the length is less than the threshold value, is automatically erased when adding the wiring 4. Thus, since the divided line shorter than the threshold value is erased as excess wiring and the long divided line is not erased because of the necessity of required wiring, the number of operations for enlarging, reducing or moving the display picture of a wiring pattern is reduced. Thus, the wiring design can be easily executed in a short time.

CONSTITUTION:Segments (11 and 12 or 13 and 14) are lead out into X and Y directions from each terminal and a minimum rectangle (15 or 16) including it is obtained. The segments are searched for from an empty segment list. Then, a center point and a circumscribed circle radius of each rectangle are obtained and the center of each rectangle is set to O1-O3 and the radius of the circumscribed circle is set to r1-r3. Then, the distance between the centers d12 and d13 from a circumscribed circle with the terminal 1 and other circumscribed circle is obtained. F1j calculated from an expression for obtaining the positional relationship of the circumscribed circle, namely F1j=dij-(r1+rj), is sorted in the ascending order. Then, the terminal wiring order is determined by that order. Finally, a detailed wiring is performed by using an empty segment according to the wiring order.

摘要： PURPOSE:To perform a cooling mode operation at a low temperature by controlling both temperature and humidity as the humidity is given priority. CONSTITUTION:When a humidity controller 24 is closed and a temperature controller 25 is opened, a coil 7A of an electromagnetic switch for room unit fan a coil 5A of an electromagnetic switch for compressor are electified to allow a cooling mode operation. When a cooling mode operation at a low temperature is to be performed, a deicer 19 detects the temperature of an intake pipe. If the temperature becomes lower than a set value and the time as counted by a timer exceeds a certain time, the electrification of the coil 7A of the electromagnetic switch is interrupted to stop the room unit fan 2, and a defrosting mode operation is started after a solenoid valve 21 and a defrosting lamp 20 are activated. In this manner, a suitable temperature management can be made for objects to be dehumidified, and the reliability of the system can be improved.
