Abstract

PURPOSE:To attempt to carry out optimum control of the humidity during the space heating operation by providing a timer region which turns ON the humidifier and a timer region which forcibly turns OFF the humidifier. CONSTITUTION:The condition part which determines the ON/OFF of the humidifier comprises a first condition part which discriminates whether a thermostat determined by a room temperature sensor 2 and a room temperature setting part 3, is ON or not; a third condition part which discriminates whether the temperature detected by the room sensor 2 is more than a predetermined value or not; and a fourth condition part which discriminates the relative humidity detected by a humidity sensor 5 is less than a predetermined value or not. In the case where the system is in a timer region 1 the humidifier is turned ON only when the first through third conditions are all satisfied. In the case where the system is in a timer region 2, the humidifier is turned ON only when the first through fourth conditions are all satisfied. When the system is in a timer region 3 and when the system is in timer regions 1 and 2 and any unestablished condition exists, the humidifier is turned OFF. As a result, a constantly moderate humidity can be maintained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is mainly applied when a humidifier is used in conjunction with a heat pump type air conditioner for heating.

Conventional configuration and its problems Conventionally, when using a heat pump air conditioner for heating,
As the room temperature rose, the relative humidity in the room decreased, causing the room to become too dry.

In addition, in recent years, separate humidifiers have been increasingly used to prevent this dryness, but it is difficult to ideally control the relationship between air conditioning conditions and the amount of humidification, and excessive humidification tends to occur. There was a problem in which large amounts of dew condensed on walls and windows when the room temperature dropped.

A configuration in which a humidifier is equipped with a humidity sensor for control has also been considered, but the difference in humidity distribution between the vicinity of the humidifier and each part of the room is large, making ideal humidity control impossible.

Purpose of the Invention The present invention aims to perform more optimal humidity control during heating, organically linking air conditioner control conditions and humidifier control, and aims for more comprehensive ideal air conditioning. .

In order to achieve this object, the present invention includes a control device that uses a room temperature sensor, a room temperature setting section, an operation switch, and a humidity sensor as input sources and controls an actuator section and a humidifier control section. The control device includes a second condition unit that determines whether the operation switch is for heating or not, and a second condition unit that determines whether the temperature detected by the room temperature sensor is lower than the temperature set by the room temperature setting unit, which is detected by the room temperature sensor. a third condition section for determining whether the indoor temperature to be detected is at least a predetermined value; and a fourth condition section for determining whether the humidity detected by the humidity sensor is at most a predetermined value; Turn on the humidifier only when the conditional part and the third conditional part are satisfied. Humidify only when the timer area 1, the first conditional part, the second conditional part, the third conditional part, and the fourth conditional part are all satisfied. Timer area 2 to turn on the humidifier, timer area 3 to force the humidifier to OFV
The timer area 1.2.3 is configured to repeat and continue.

DESCRIPTION OF EMBODIMENTS Regarding one embodiment of the humidifier control device according to the present invention, the first embodiment will be explained below.
This will be explained using the control circuit block diagram shown in the figure, the control flowchart shown in FIG. 2, and the timer diagram shown in FIG. 3.

First, the circuit configuration will be explained with reference to the control circuit block diagram shown in FIG. Here 1 is a microcomputer (
2 is a room temperature sensor, 3 is a room temperature setting section, 4 is an operation switch, 5 is a humidity sensor, 6 is a system clock section of the microcomputer 1, 7 is an air conditioner such as a compressor, fan motor, valve, etc. The actuator section 8 used for control is a humidifier control section.

The microcomputer 1 uses the room temperature sensor 2, the room temperature setting section 3, and the operation switch 4 as inputs, and uses the actuator section 7 as an output to perform general control of the air conditioner.

Further, the humidifier is controlled using the room temperature sensor 2, room temperature setting section 3, operation switch 4, and humidity sensor 5 as inputs, and the humidifier control section 8 as output.

Next, the operation of the humidifier control device will be explained using FIG. 2.

This figure is a flowchart of the humidifier control part in the air conditioner.

The condition section for determining ○N/○FF of the humidifier is configured as follows.

That is, a first condition section determines whether heating is in progress, a second condition section determines whether the thermostand is ON or not, which is determined by the room temperature sensor 2 and the room temperature setting section 3; The detected temperature is T1°C
It consists of a third condition part that determines whether or not the above is true, and a fourth condition part that determines whether the relative humidity detected by the humidity sensor is A% or less.

Here, the condition part is changed to the area IU of the continuous timer area shown in FIG.

When in timer area 1 shown in FIG.
Turn on the humidifier only when all conditions are met. When in timer region 2, the humidifier is turned on only when all of the first to fourth conditions are satisfied. Further, the humidifier is turned off when it is in the timer area 3 and when there is an unfulfilled condition in the timer area 1.2.

Next, each condition part will be explained.

The conditions under which the humidifier needs to be turned on are: (1) The room temperature is on a rising trend under heating conditions, which means that the relative humidity is on a downward trend from now on. (2) The room temperature is above a certain level, that is. (3) The relative humidity is actually low when normal heating operation is performed and the relative humidity has fallen below the allowable value.

If we adopt a configuration in which the humidifier is controlled only by relative humidity, (1) the distribution of relative humidity will cause variations in the settings (i) (2) variations in humidity sensors, temperature characteristics, aging However, if foreign matter adhesion is taken into account, there will be large variations in the settings. (3) If the humidity sensor fails, problems will occur because there is no guaranteed function.

Therefore, in the present invention, the timer area 2 in which all the humidifier ON conditions are AND conditions and the ON conditions other than the humidity sensor are A.
Timer area 1 as ND condition and forced humidifier OFF
By providing the timer area 3, excessive humidification is suppressed and an appropriate amount of humidification is ensured.

Effects of the Invention According to the present invention, a decrease in relative humidity during heating can be prevented by humidification, and by controlling it in relation to air conditioning conditions, it is possible to always maintain a moderate relative humidity, and it is possible to prevent a decrease in relative humidity due to excessive humidification. It is possible to minimize condensation on the wall when the heating operation is stopped.

In addition, the influence of variations in humidity sensors due to various causes can be minimized, and together with temperature control in air conditioners, this greatly contributes to the realization of ideal air conditioning.

Furthermore, since the feeling of heating is increased by appropriate humidification, it becomes possible to set the room temperature to a lower level, thereby contributing to energy saving.
