Problems solved by technology

[0004] Therefore, even if the indoor temperature or indoor humidity is high, the operation of the air conditioner cannot be started unless the user performs an operation start operation on the controller.
Therefore, the user is at risk of heatstroke, etc.

no. 2 Embodiment approach

[0131] Below, refer to Figure 6 A second embodiment of the present invention will be described. The air conditioner of the second embodiment differs from the air conditioner of the first embodiment in the timing at which the cooling operation is started in the forced operation mode. In addition, other configurations are the same as those of the above-mentioned first embodiment, so the same reference numerals are used and descriptions thereof are appropriately omitted.

[0132] In the air conditioner of the second embodiment, the judgment map for judging the start of the forced operation is different from the judgment map of the air conditioner 1 of the first embodiment ( Figure 4 )same.

[0133] Furthermore, in the air conditioner of the first embodiment, in the forced operation mode, the cooling operation is started when the indoor temperature and the indoor humidity are in the high temperature range, while in the air conditioner of the second embodiment, in the forced op...

no. 3 Embodiment approach

[0150] Below, refer to Figure 7 A third embodiment of the present invention will be described. The air conditioner of the third embodiment differs from the air conditioner of the first embodiment in the timing at which the cooling operation is started in the forced operation mode. In addition, other configurations are the same as those of the above-mentioned first embodiment, so the same reference numerals are used and descriptions thereof are appropriately omitted.

[0151] In the air conditioner of the third embodiment, the judgment map for judging the start of the forced operation is different from the judgment map of the air conditioner of the first embodiment ( Figure 4 )same.

[0152] Furthermore, in the air conditioner of the first embodiment, in the forced operation mode, the cooling operation is started when the indoor temperature and the indoor humidity are in a high temperature range, whereas in the air conditioner of the third embodiment, the forced operation ...

no. 4 Embodiment approach

[0169] Below, refer to Figure 8 , Figure 9 A fourth embodiment of the present invention will be described. The air conditioner of the fourth embodiment differs from the air conditioner of the first embodiment in the timing of starting the ventilation operation and the timing of starting the cooling operation in the forced operation mode. In addition, other configurations are the same as those of the above-mentioned first embodiment, so the same reference numerals are used and descriptions thereof are appropriately omitted.

[0170] In the air conditioner of the fourth embodiment, the judgment map for judging the start of the cooling operation uses Figure 8 The decision diagram shown. The vertical axis of the judgment graph represents indoor humidity (relative humidity), and the horizontal axis represents indoor temperature.

[0171] like Figure 8 As shown, a high temperature area and a standby area are set in the judgment map. Figure 8 The shown high temperature are...

Abstract

Provided is an air-conditioner. Under states that indoor temperature or indoor humidity are relatively high, when the operation is shut down, the air-conditioner can automatically start mandatory operation which reduces at least one of the indoor temperature and the indoor humidity. An indoor unit of the air-conditioner is provided with an indoor temperature sensor and an indoor humidity sensor. When operation stops, in a mandatory operation mode, the air-conditioner automatically starts refrigeration operation in situations that the indoor temperature detected by the indoor temperature sensor and the indoor humidity detected by the indoor humidity sensor are in a high temperature area.

Description

technical field [0001] The present invention relates to an air conditioner that performs cooling operation and the like. Background technique [0002] The air conditioner normally performs cooling operation, heating operation, etc., and when the user selects cooling operation, etc. on the controller and performs an operation start operation, the cooling operation, etc., starts. [0003] [Patent Document 1] Japanese Patent Laid-Open No. 2009-168372 [0004] Therefore, even in a state where the indoor temperature or indoor humidity is high, the operation of the air conditioner cannot be started unless the user performs an operation start operation on the controller. Therefore, there is a possibility that the user suffers from heat stroke or the like. Contents of the invention [0005] Therefore, an object of the present invention is to provide an air conditioner capable of automatically starting forced operation to lower at least one of indoor temperature and indoor humidi...
