Embodiment approach 1

[0024] figure 1 is a conceptual diagram showing a board assembly of a control board used in a control unit of the air-conditioning control system according to Embodiment 1, figure 2 It is a figure which shows the air-conditioning control system of Embodiment 1, image 3 It is a flowchart showing the control method in the air-conditioning control system of Embodiment 1. The control board of the air-conditioning control system of the present embodiment controls the air-conditioning without malfunctioning in a low-temperature environment lower than the temperature guaranteed by the manufacturer of electronic components such as the microcomputer 12 . The control board 10 of the present embodiment is equipped with a power circuit unit 11 and a microcomputer 12 connected to the power circuit unit 11, and is provided with: a temperature sensor 13 that detects the ambient temperature of the microcomputer 12; device 14, and the heater 14 heats the microcomputer 12. It is characteri...

Embodiment approach 2

[0046] In the first embodiment above, the heater 14 itself for heating the control board is controlled to switch to the heat generation mode, but in the second embodiment, the heater 14 is not separately provided, and the indoor unit connected to the outdoor unit 1 is controlled. 2 load is adjusted, the power supply circuit unit 11 is heated, and electronic components such as the microcomputer 12 are heated. Figure 4 is a conceptual diagram showing a board assembly of a control board used in a control unit of an air-conditioning control system according to Embodiment 2, Figure 5 It is a figure which shows the air-conditioning control system of Embodiment 2, Image 6 It is a flowchart showing the control method in the air-conditioning control system of Embodiment 2. The control board 10S, which is a board assembly of the outdoor unit 1, does not have the heater 14 for heating the microcomputer 12, and operates many actuators in the circuit for supplying power to the indoor u...

Embodiment approach 3

[0060] In Embodiments 1 and 2 above, in order that the temperature sensor 13 always detects the ambient temperature even when the operation is stopped, the operation can be restarted immediately, and control is performed so that the ambient temperature becomes the temperature T 0 Above, but in order to increase the ambient temperature, excess power is always consumed continuously. Therefore, in Embodiment 3, control is performed to suppress power consumption when the operation is stopped. In this embodiment, an operation reservation timer is provided to reserve the operation time. When the operation is stopped, the temperature detection of the electronic components by the temperature sensor 13 is stopped, and the microcomputer 12 is controlled to turn on the timer at the time when the operation reservation is set. Wait for the electronic components to become above the guaranteed temperature. Figure 8 A time chart showing the method of Embodiment 3 is shown.

Abstract

An air-conditioning control system is obtained, comprising: an air-conditioning main body, the air-conditioning main body having an air-conditioning function; a power supply circuit part (11); a control substrate (10), the control substrate (10) being equipped with electronic components, and the electronic The component includes a microcomputer (12) for control; a temperature sensor (13), which measures the temperature of the electronic component; The electronic components are heated so as to operate at or above the guaranteed temperature of the electronic components. Therefore, the air conditioner can always use the target member within the manufacturer's guaranteed temperature range during normal operation.

Description

technical field [0001] The present invention relates to an air-conditioning control system and an air-conditioning control method, in particular to an air-conditioning system equipped with a temperature control function used in low-temperature environments such as cold regions. Background technique [0002] Conventionally, depending on the air conditioner placed outdoors, it may be used in an environment where the outside air temperature is low, such as in a cold region. In such a low-temperature environment, electronic components such as microcomputers mounted on substrate assemblies (ASSY: assembly), that is, substrate assembly mounting components, are sometimes used at temperatures lower than the guarantee temperature (Japanese: guarantee temperature) of the component manufacturer, and electronic components have Malfunction may occur. [0003] Therefore, Patent Document 1 discloses a technology in which when the ambient temperature is lower than the range guaranteed by t...
