[0042] First, use Figure 1 to Figure 5 The outline of the structure and operation|movement of the air conditioner which concerns on 1st Embodiment of this invention is demonstrated. figure 1 and figure 2 It is a schematic configuration diagram of the air conditioner, showing the states of the heating operation and the cooling operation, respectively. image 3 It is a perspective view of the appearance of the indoor unit of the air conditioner, Figure 4 It is the front view of the display part of the indoor unit, Figure 5 It is a block diagram showing the configuration of the air conditioner.

[0043] Air conditioner 1 is a separate air conditioner, such as figure 1 and figure 2 Shown is composed of an outdoor unit 10 and an indoor unit 30 .

[0044] The outdoor unit 10 is installed on the ground outside, for example, and has a rectangular box-shaped housing 11 made of synthetic resin members and metal plate members. A compressor 12 , a switching valve 13 , an expansi...

[0081] Next, use Figure 7 , and an air conditioner according to a second embodiment of the present invention will be described. Figure 7 It is a flowchart showing the operation flow of the air conditioner during heating operation. In addition, due to the basic structure and utilization of the above-mentioned embodiment Figure 1 to Figure 6 The first embodiment described above is the same, so the same reference numerals are used for the same components as those of the first embodiment, and descriptions and explanations in the drawings are omitted.

[0082] The air conditioner 1 of the second embodiment is the same as the first embodiment, and has a heating operation mode in which the heating operation is automatically temporarily stopped when the outside air temperature is extremely low, and then when the heating operation is restarted, defrosting is performed first. After the operation, restart the heating operation. However, instead of using the temperature detector 27 ...

Abstract

The air conditioner (1) is provided with an outdoor unit (10) and an indoor unit (30). The outdoor unit (10) is provided with: an outdoor heat exchanger (16), a compressor (11), an outdoor fan (15), a temperature detector (23) for detecting the temperature of the outdoor heat exchanger (16), and a temperature detector (27) for detecting the outdoor temperature. The indoor unit (30) is provided with an indoor heat exchanger (33) and an indoor fan (32). The air conditioner (1) has a heating operation mode wherein the air conditioner stops heating operation and goes to standby when the outdoor temperature reaches a temperature at or below a previously established first specified temperature during heating operation and when the outdoor temperature subsequently reaches a temperature at or above a previously established second specified temperature that is higher than the first specified temperature, resumes heating operation after executing a defrost operation.

Description

technical field [0001] The present invention relates to an air conditioner. Background technique [0002] Household air conditioners adopt the heat pump system, and the mainstream is a separate type that is divided into an outdoor unit and an indoor unit. Furthermore, Patent Document 1 discloses an air conditioner that automatically stops the heating operation when the outside air temperature is, for example, an extremely low temperature below -15°C. [0003] The conventional air conditioner described in Patent Document 1 stops the compressor and the outdoor air blower and operates the indoor air blower as a circulator when the outside air temperature exceeds the usable temperature range of the apparatus. Thus, damage to the compressor and the outdoor heat exchanger can be prevented, and comfort can be improved by circulating indoor air. [0004] Patent Document 1: Japanese Patent Laid-Open Publication No. Hei 5-346257 [0005] Generally speaking, when the above-mentioned...
