Abstract

An air conditioner selectively executes a first control which carries out an air conditioning by driving a compressor by a frequency which is controlled based on a set value and a space temperature, and a second control which carries out an air conditioning with a predetermined air conditioning capacity. The operating apparatus switches an activeness and an inactiveness of a signal based on a scale relationship between the space temperature and the set temperature. An instructing part instructs the air conditioner to start the second control with an input to a inputting part as a trigger, and instructs the air conditioner to finish the second control with a switch of the signal as a trigger. An estimated value of the set temperature is calculated based on the space temperature with the switch of the signal as a trigger, and is transmitted as the set value to the air conditioner.

Claims

1. A mediating apparatus mediating a communication between an air conditioner and an operating apparatus, said air conditioner selectively executing a first air conditioning control and a second air condition control, said first air conditioning control carrying out an air conditioning while including a step of driving a compressor by a frequency which is controlled based on a set value and a space temperature of a space being an object of an air conditioning control, and reducing said frequency, said second air conditioning control carrying out an air conditioning with a predetermined air conditioning capacity, and said operating apparatus inputting a set temperature, and switching an activeness and an inactiveness of a signal based on a scale relationship between said space temperature and said set temperature and transmitting said signal, the mediating apparatus comprising:

an inputting part for making said air conditioner execute said second air conditioning control;

a signal receiving part which receives said signal from said operating apparatus;

an instructing part which instructs said air conditioner to start said second air conditioning control with an input to said inputting part as a trigger, and instructs said air conditioner to finish said second air conditioning control with a switch of the activeness and the inactiveness of said signal as a trigger;

a room temperature acquiring part which receives an information indicating said space temperature;

a set temperature estimating part which calculates an estimated value of said set temperature based on said space temperature with the switch of the activeness and the inactiveness of said signal as a trigger; and

an estimated value transmitting part which transmits said estimated value as said set value to said air conditioner.

2. The mediating apparatus as claimed in claim 1, wherein said predetermined air conditioning capacity is equal to or more than an average value of the air conditioning capacity which is output by said first air conditioning control during a period between a first time point and a second time point, the activeness and the inactiveness of said signal being switched at said second time point, said second time point being just before said first time point when the input to said inputting part is carried out.

3. The mediating apparatus as claimed in claim 2, wherein said operating apparatus activates and transmits said signal when said space temperature is lower than said set temperature in the case that said air conditioner executes a cooling operation, and activates and transmits said signal when said space temperature is higher than said set temperature in the case that said air conditioner executes a heating operation, and

wherein said instructing part instructs said start of said second air conditioning control only in the case that said signal is activated.

4. The mediating apparatus as claimed in claim 1, further comprising a second inputting part for making said air conditioner carry out a third air conditioning control which carries out the air conditioning with a second air conditioning capacity which is smaller than said predetermined air conditioning capacity,

wherein said instructing part instructs said air conditioner to start said third air conditioning control with the input to said second inputting part as a trigger, and instructs said air conditioner to finish said third air conditioning control with the switch of the activeness and the inactiveness of said signal as a trigger.

5. The mediating apparatus as claimed in claim 2, further comprising a second inputting part for making said air conditioner carry out a third air conditioning control which carries out the air conditioning with a second air conditioning capacity which is smaller than said predetermined air conditioning capacity,

wherein said instructing part instructs said air conditioner to start said third air conditioning control with the input to said second inputting part as a trigger, and instructs said air conditioner to finish said third air conditioning control with the switch of the activeness and the inactiveness of said signal as a trigger.

6. The mediating apparatus as claimed in claim 3, further comprising a second inputting part for making said air conditioner carry out a third air conditioning control which carries out the air conditioning with a second air conditioning capacity which is smaller than said predetermined air conditioning capacity,

wherein said instructing part instructs said air conditioner to start said third air conditioning control with the input to said second inputting part as a trigger, and instructs said air conditioner to finish said third air conditioning control with the switch of the activeness and the inactiveness of said signal as a trigger.

7. The mediating apparatus as claimed in claim 1, wherein said instructing part instructs said air conditioner to start said second air conditioning control with the input to said inputting part as a trigger at a time when said signal is active, instructs said air conditioner to start a third air conditioning control which carries out the air conditioning with a second air conditioning capacity which is smaller than said predetermined air conditioning capacity with the input to said inputting part as a trigger at a time when said signal is inactive, and instructs said air conditioner to finish said second air conditioning control or the third air conditioning control with the switch of the activeness and the inactiveness of said signal as a trigger.

8. The mediating apparatus as claimed in claim 2, wherein said instructing part instructs said air conditioner to start said second air conditioning control with the input to said inputting part as a trigger at a time when said signal is active, instructs said air conditioner to start a third air conditioning control which carries out the air conditioning with a second air conditioning capacity which is smaller than said predetermined air conditioning capacity with the input to said inputting part as a trigger at a time when said signal is inactive, and instructs said air conditioner to finish said second air conditioning control or the third air conditioning control with the switch of the activeness and the inactiveness of said signal as a trigger.

9. The mediating apparatus as claimed in claim 3, wherein said instructing part instructs said air conditioner to start said second air conditioning control with the input to said inputting part as a trigger at a time when said signal is active, instructs said air conditioner to start a third air conditioning control which carries out the air conditioning with a second air conditioning capacity which is smaller than said predetermined air conditioning capacity with the input to said inputting part as a trigger at a time when said signal is inactive, and instructs said air conditioner to finish said second air conditioning control or the third air conditioning control with the switch of the activeness and the inactiveness of said signal as a trigger.

10. An air conditioning system comprising:

an air conditioner selectively executing a first air conditioning control and a second air conditioning control, said first conditioning control carrying out an air conditioning while including a step of driving a compressor by a frequency which is controlled based on a set value and a space temperature of a space as a subject of an air conditioning control, and reducing said frequency, and said second air conditioning control carrying out an air conditioning with a predetermined air conditioning capacity;

an operating apparatus inputting a set temperature, and switching an activeness and an inactiveness of a signal based on a scale relationship between said space temperature and said set temperature and transmitting said signal; and
