Abstract

PURPOSE:To get a superior air conditioning environment at any installing height and in any operating condition by a method wherein the number of revolutions of a blower is determined in response to an installing condition and an operating condition and a fan motor driving circuit for use in driving the blower at this number of revolutions is provided. CONSTITUTION:An installation setting switch 13 is set after installing an indoor device in response to whether the indoor device installation is at a ceiling recess or a floor recess. An input signal from an installing height setting switch 13 is received and the number of revolutions control means 14 of a micro-computer configuration determines the number of revolution and controls it. If the operation setting is 'heating' and an installing setting is 'a ceiling recess', the number of revolution of an blower 11 is set in such a way as it has a set amount of blown air + alpha. The number of revolution is set to the most suitable number of revolution in such a way as a hot air got from the air blower is sufficiently reached to a floor surface to keep a temperature distribution and then a capability and an efficiency of target value are fulfilled. If the installing setting is 'floor recess', the set amount of air is not varied. In this way, the number of revolutions is set and the air volume is varied such that a comfortable air flow environment may always be assured under each of the installing setting and an operation setting.

First, depending on the installation height of the guide unit, whether it is installed on the top of the wall like a conventional wall-mounted type or near the floor like a floor-standing type, the installation height setting switch ■ is set for the indoor unit. Set after installation. In response to the input signal from this height setting switch (2), the rotation speed determining means with a microcomputer configuration determines the total rotation speed at which the upper and lower blowers should be operated.

[Problem to be solved by the invention]

As described above, in the conventional 9-air conditioner, the air volume is fully controlled based on the installation height, so the control included in 1 of the air volume control based on the operation settings of the 9-air conditioner was not performed.

For this reason, for example, when installed on the upper part of a wall, warm air reaches the floor during heating, but when cooling, the cold air is so strong that you feel cold.

This invention was made to solve all of the above-mentioned problems, and it can be installed without limiting the installation position, and a good air-conditioned environment can be obtained at any installation height and in any operating condition! The aim is to provide a complete range of air conditioners.

[Means to solve the problem]

The present invention provides an installation position setting means for inputting the installation position conditions of the indoor unit of the sanity conditioner, and uses the input from this means and the determination of the operation settings in 11. The number of rotations of the blower can be set.

[Effect]

Depending on the structure of this invention, it is a large bag. In the nitrogen air conditioner that can be installed on the ground side, it is possible to always obtain a good temperature distribution regardless of the installation position and operating conditions of the air conditioner.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

Figure 3 shows the installation setting switch, which is used to input whether the indoor unit is to be installed in a large bag or a plain bag.

Next, the operation of the above embodiment will be explained.

First, depending on whether the indoor unit is installed in a large bag or a plain bag, the installation setting switch a3 is set after the indoor unit is installed. In response to the input signal from this installation height setting switch fi3, the rotation speed control means α is configured by a microcomputer.
The water determines and controls the rotation speed.

This is shown in a flowchart as shown in FIG. The operation will be explained below using this flowchart.

1. Enter the installation setting switch in Stella 7 (411). At step C, if the operation setting is 1 heating, proceed to step (c); if the operation setting is other than heating, return to step U.

If the installation setting force is 1 large bag with a step tin, then the step is false, and the rotation speed of the blower (llll) is set so that the set air volume + α. The optimal rotation speed is set to reach the floor surface, ensure temperature distribution, and satisfy the target performance and efficiency.

If the installation setting is "0" in step (to), the flow goes back to step 4p and the setting wind i is not changed.In this way, depending on the installation setting switch, a comfortable airflow environment is always maintained in each installation setting and operation setting. The rotation speed is set and the air volume is changed so as to maintain the rotation speed.

〔Effect of the invention〕
