Abstract

[PROBLEMS] To select an energy saving method for an air conditioner by switching between a normal mode and an energy saving mode with SW, and in the energy saving mode, an outside air temperature and a uniquely determined reference outside air temperature are input and set from these deviations. Because the temperature is determined, the desired set temperature will not be reached indefinitely during cooling operation with a low outdoor temperature and a large indoor load, or during a heating operation with a high outdoor temperature and a large indoor load. I couldn't harmonize.
By enabling the user to set the upper limit value of the frequency of the variable capacity compressor 1 from the remote controller 6, air conditioning can be performed in accordance with the remote controller set temperature desired by the user and the indoor required load. And it becomes possible to bring about an energy saving effect.

Description

  The present invention relates to a remote controller for an air conditioner that obtains an energy saving effect by setting an upper limit value of the frequency of the variable capacity compressor of the air conditioner from the remote controller.

  The conventional air conditioner energy saving method is to switch between normal mode and energy saving mode with SW, and input the outside air temperature and the standard outside air temperature uniquely determined in the energy saving mode, and set the temperature from these deviations. (For example, refer to Patent Document 1).

The flowchart of FIG. 4 shows connection abnormality control of the conventional air conditioner described in Patent Document 1. As shown in the flowchart of FIG. 4, the energy saving mode determination unit 101, the temperature setting unit 102, the outside air temperature input unit 103, the operation mode determination unit 104, the uniquely determined outside air temperature, and the current outside air temperature. Cooling time comparison means 106, heating time comparison means 110, cooling time temperature setting means 105 that uniquely defines the outside air temperature -5K from the outside air temperature, heating time temperature setting means 109 that is defined as the outside air temperature + 5K, and cooling time comparison A means 108 for determining the temperature setting when judged to be higher than the outside air temperature uniquely determined by the means 106 and a temperature setting for when judged to be lower than the outside air temperature uniquely determined by the heating comparison means 110 are determined. It is comprised from the means 111 to perform, and the compressor control 113 according to preset temperature, the rush of energy saving mode is performed by SW, and at the time of energy saving mode And it determines the set temperature the current outside air temperature as input.

  However, in the above-described conventional configuration, the set temperature is determined from the current outside air temperature state based on a uniquely determined outside air temperature threshold value. At the time of heating operation with a large indoor load due to temperature, there has been a problem that the desired set temperature is not reached forever and air conditioning according to the required load cannot be performed.

  The present invention solves the above-described conventional problems, and allows the user to set the upper limit value of the frequency of the variable capacity compressor from the remote controller, and adjusts the air conditioning according to the remote controller set temperature desired by the user and the indoor required load. An object is to provide an air conditioner that can perform energy saving effects.

  In order to solve the above-described conventional problems, an air conditioner of the present invention is connected to an outdoor unit having a variable capacity compressor, a communication line connecting the outdoor unit and the indoor unit, and the variable capacity compressor An energy saving operation is performed by setting an upper limit value of the frequency of the variable capacity compressor from a remote controller having an upper limit frequency setting means for setting an upper limit value of the frequency.

  Thus, when the upper limit frequency is set, only the operation up to the upper limit frequency desired by the user is performed, so that an energy saving effect can be brought about by lowering the capacity variable compressor operation frequency.

Since the air conditioner of the present invention only operates up to the upper limit frequency desired by the user when the upper limit frequency is set, it is possible to bring about an energy saving effect by lowering the capacity variable compressor operation frequency.

  1st invention has the upper limit frequency setting means which connects the outdoor unit which has a capability variable type compressor, an outdoor unit and an indoor unit with a communication line, and sets the upper limit of the frequency of a capability variable type compressor By using an air conditioner composed of a remote control, the user can only operate up to the upper limit frequency set by the upper limit frequency setting means, so reducing the operating frequency of the variable capacity compressor can bring about an energy saving effect. it can.

  According to the second aspect of the invention, in particular, the remote control having the upper limit frequency setting means of the first invention has a display means capable of displaying that the upper limit frequency is being set, thereby setting the upper limit frequency to the user. I can let you know.

  In the third aspect of the invention, in particular, the remote controller having the upper limit frequency setting means of the first invention is provided with level setting means capable of setting the upper limit frequency level, so that the user sets the upper limit frequency level. You can set the level of energy saving effect.
