摘要： PURPOSE:To reduce the fluctuation of cooling/heating capacity by controlling the compressor frequency based on the temperature of the indoor heat exchanger and providing a data compensating timer respectively for compressor frequency control, damper control and air supply rate control. CONSTITUTION:In a duct type air conditioner 20, the operating frequency of the compressor 21 is controlled through an inverter 31 in response to the temperature of the indoor heat exchanger 23 as measured by a temperature sensor 34. The central processing unit 36 has a data compensating timer which regulates the variable capacity compressor 21, dampers 28a-28d and fan 30 respectively when they have not been controlled for a specified time interval so as to reduce the fluctuation of cooling/heating capacity. Also, the temperature fluctuation in respective rooms can be reduced by maintaining the opening of the dampers 28a-28d within a specified range less than the fully opened position and increasing the air supply rate by the fan 30. Moreover, the set temperature of the indoor heat exchanger 23 is regulated to suit the air conditioning load so as to make the low load operation highly efficient. Thus, the fluctuation of cooling/heating capacity can be reduced.

摘要： PURPOSE:To perform the optimum air-conditioning in conformity with the environment and circumstances of a plurality of rooms and to improve the operation efficiency by a method wherein a blast amount to each room and working frequency are controlled, and during zone shift control along with lapse of a time, regulation of a blast amount is imparted with priority over the control of working frequency. CONSTITUTION:During cooling operation, a control part 50 and terminal controllers 51-53 calculate a difference between detecting temperatures by indoor temperature sensors 61-63 and a set indoor temperature, and according to a calculated result, the openings of dampers 21-23 and working frequency are controlled. In the circumstances in which a temperature difference is high, the opening of the damper 21 is increased, and a blast amount to a room 11 is increased. When the same zone is continued for a specified time, zone shift by an amount equivalent to a given step is effected for correction. The opening of each damper is converted to an opening value, and zone shift control is effected in a stepped manner on working frequency according to the total sum of the opening values. In this case, a specified time condition is set, and a changing in an opening is imparted with a priority over the changing in working frequency.

摘要： PURPOSE:To decide necessary capacity of a system, vary setting of a temperature in a room, and improve rise response during the fluctuation of a load by a method wherein according to a difference between the room temperature of each room and a set temperature, the opening of each damper is decided and the number of revolutions of the compressor of a freezing circuit is controlled according to the maximum value of a damper opening. CONSTITUTION:A difference between temperature measurement from a room temperature sensor 31 and the set temperature of a temperature setter 32 is detected by a temperature difference detector 33. Based on a detected temperature difference, the opening of a damper is set by means of a damper opening setter 34, and the opening of the damper is set by means of a damper motor 35. Outputs VA, VB, and VC proportioning to damper openings phiA, phiB, and phiC are outputted from damper controllers 36, 37, and 38, respectively. In an indoor unit controller, each signal is converted into digital signals thetaA, thetaB, and thetaC by means of AD converters 41, 42, and 43, and a result is read by means a microcomputer 44 and produces a signal thetaMAX for a maximum opening. From an opening specified zone, the microcomputer decides in which region the signal thetaMAX is provided, and varies a frequency command to an inverter. An inverter 40 changes the number of revolutions of a compressor 16 according to an output frequency.

摘要： PURPOSE:To get a fast rising in temperature when an operation is started and to reduce a power consumption by a method wherein each of heating operations with an indoor heat exchanger only, a parallel circuit of the indoor heat exchanger and a radiation heat exchanger, a series circuit of the radiation heat exchanger and the indoor heat exchanger and the radiation heat exchanger is properly selected in response to a load. CONSTITUTION:At the time of starting operation, there is a substantial difference between an indoor air temperature and a set indoor air temperature, so that refrigerant discharged from a compressor 21 is flowed from a four-way valve 22, a two-way valve 23, an indoor heat exchanger 24, an expansion valve 25 and an outdoor heat exchanger 26 in this order and then a powerful hot air heating only with radiation of the indoor heat exchanger 24 is carried out. As the indoor temperature is increased and the difference between it and the set indoor air temperature is reduced, a part of the refrigerant passed through the four-way valve 22 passes through the two-way valve 27, radiation heat exchanger 28a and an expansion valve 29, merged with a flow of refrigerant flowing to the outdoor heat exchanger 26 and thus hot air heating and radiation heating are concurrently carried out. As the indoor air temperature approaches the set indoor air temperature, the refrigerant flows in the series circuit of the radiation heat exchanger 28a and the indoor heat exchanger 24 and then the hot air heating and the radiation heating are concurrently carried out. As the indoor air temperature reaches or exceeds the set indoor air temperature, only the radiation heating is carried out.

摘要： PURPOSE:To prevent a dew from being generated, any dripping into an air conditioned room and further improve a reliability and a convenience in use by a method wherein a dew preventing grill is arranged between a blowing duct and a panel blowing port so as to prevent cold air blown from being abutted against both ends of the panel blowing port. CONSTITUTION:Warm air within an air conditioned room R is sucked from a suction port 5 into a main body 1 of an air conditioner, where the air is heat exchanged to generate a cold air. A partial hot moisture air is made into an induced air by a cold air blown from a panel blowing port 6 so as to heat both ends of the panel blowing port 6. However, the air is not directly contacted with the cold air. That is, even if the louvers 7 and 7 are set in their substantial horizontal stage, the cold air blown from the blowing port 8 toward both ends of a longitudinal direction of the panel blowing port 6 is guided by the dew preventing grills 10 and 10 and blown into the air conditioned room R. The buffle plates 12 and 12 arranged at the louvers 7 and 7 may prevent any leakage of cold air fed from a recess 11 of the dew preventing grill 10. Accordingly, the cold air is not guided to both ends of the panel blowing port 6, but even if this part is heated by the induced air, there is no formation of dew.

摘要： PURPOSE:To make possible an optimum air conditioning operation at all times irrespective of the number of operation rooms by a method wherein two-way valves connected to the input and output sides of a heat exchanger in non-operational indoor device are constituted to be opened and closed controllably in accordance with the operational condition of a refrigerating cycle. CONSTITUTION:When a controller 8 receives a signal, which indicates the shortage of refrigerant, from a temperature sensor 7, a two-way valve of one of other indoor devices, for example, a two-way valve 52c of an indoor device 52 is opened by a predetermined period of time and is controlled so as to lower an outlet temperature by the supply of the refrigerant. When the short state of the refrigerant still continues under this condition, the two-way valve 52c is opened again by a predetermined period of time in the same manner and is controlled so as to repeat this method several times at regular intervals until the outlet temperature is lowered down to a detected temperature or below. On the contrary, when the outlet temperature is too low and it is indicated that the refrigerant is in an excessive state, a two-way valve 52b on the inlet side of a heat exchanger 52a is brought into an open state by a predetermined period of time to accumulate the excessive refrigerant into the indoor device 52 so that the outlet temperature is increased to secure the optimum operation of an air conditioner.
