Abstract

[PROBLEMS] To select an energy saving method for an air conditioning system 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.
The present invention solves the above-mentioned conventional problems, and the system administrator can set the upper limit value of the frequency of the variable capacity compressor 1 from the remote control device 6, which is desired by the system administrator. It is possible to provide a remote control device for an air conditioning system that can perform air conditioning according to a set temperature and a required indoor load, and that also provides an energy saving effect.

Description

  The present invention relates to a remote control device for an air conditioning system in which an upper limit value of the frequency of a variable capacity compressor of the air conditioning system is set from the remote control device to obtain an energy saving effect.

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

The flowchart of FIG. 4 shows connection abnormality control of the conventional air conditioning system 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-mentioned conventional problems, and an administrator of the air conditioning system can set an upper limit value of the frequency of the variable capacity compressor from a remote control device. An object of the present invention is to provide a remote control device for an air conditioning system that can perform air conditioning according to a required load and that also provides an energy saving effect.

  In order to solve the above-described conventional problems, the remote control device for an air conditioning system according to the present invention is connected to an outdoor unit having a variable capacity compressor by a communication line connecting the outdoor unit and the indoor unit, and the variable capacity. An upper limit value of the frequency of the variable capacity compressor is set from a remote control device having an upper limit frequency setting means for setting an upper limit value of the frequency of the type compressor.

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

Since the remote control device of the air conditioning system of the present invention only operates up to the upper limit frequency desired by the system administrator when the upper limit frequency is set, it can bring about an energy saving effect by lowering the operating frequency of the variable capacity compressor. it can.

  According to a first aspect of the present invention, an outdoor unit having a variable capacity compressor, an outdoor unit and an indoor unit are connected by a communication line, and a plurality of connected indoor units can be controlled. By operating as a remote control device of an air conditioning system comprising a remote control device having an upper limit frequency setting means for setting an upper limit value of the frequency of the system, operation up to the upper limit frequency set by the system administrator by the upper limit frequency setting means However, the energy-saving effect of the air conditioning system can be brought about by reducing the operating frequency of the variable capacity compressor.

  According to the second aspect of the invention, in particular, the remote control device having the upper limit frequency setting means of the first invention is provided with a display means capable of displaying that the upper limit frequency is being set. It can inform you that the frequency has been set.

  According to the third aspect of the invention, in particular, the remote control device 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 system administrator can set the upper limit frequency level. Can be set, and the level of energy saving effect can be set.
