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 Structure and Problems Conventionally, when a heat pump type air conditioner is used for heating, there has been a problem that as the room temperature rises, the relative humidity in the room decreases, resulting in excessive dryness.

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 where a large amount of condensation formed on the 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 to achieve more comprehensive ideal air conditioning. It is.

Structure of the Invention In order to achieve this object, the present invention includes a control device that controls an actuator section including a compressor and a humidifier control section, and the control device determines whether or not the operation mode set by the operation switch is heating. a first condition part that determines whether the thermostat for compressor operation is ON, which determines whether the temperature detected by the room temperature sensor is determined by the temperature set in the room temperature setting part, and the room temperature sensor. a third condition section that determines whether the indoor temperature detected by the humidity sensor is equal to or higher than a predetermined value; and a fourth condition section that determines whether the detected humidity of the humidity sensor is equal to or lower than the predetermined value; Turns the output ON only when all of the following are true.
The configuration is as follows.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the humidifier control device according to the present invention will be described with reference to the control circuit block diagram shown in FIG. 1 and the control flowchart shown in FIG. 2.

First, from the control circuit block diagram in Figure 1,
The circuit configuration will be explained. Here, 1 is a microcomputer (control device), 2 is a room temperature sensor, and 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 actuator section used to control the air conditioner such as a compressor, fan motor, valve, etc., and 8 is a humidifier. This is the device 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 including the compressor as an output to perform general control of the air conditioner.

The humidifier is controlled using the room temperature sensor 2, sensor setting section 3, operation switch 4, and humidity sensor 5 as inputs and the humidifier control section 8 as an 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 part that determines ON/OFF of the humidifier is configured as follows.

In other words, the thermostat, which is the condition for operating the compressor included in the actuator section 7 determined by the first condition section that determines whether the heating operation is in progress, the room temperature sensor 2 and the room temperature setting section 3, is turned ON.
a second condition part that determines whether the temperature detected by the room temperature sensor 2 is T ₁ °C or more; and a third condition part that determines whether the temperature detected by the room temperature sensor 2 is T It consists of a fourth condition part that determines whether or not the condition exists.

Here, the humidifier is turned on only when all of the first to fourth conditions are satisfied. In addition, the humidifier is turned off when an unfulfilled condition exists.

Next, each condition part will be explained.

The conditions under which the humidifier needs to be turned on are: (1) Under heating conditions, the thermostat is on and the room temperature is on the rise, which means that the relative humidity is on the decline. (2) The room temperature is constant. That is, the relative humidity must have fallen below the allowable level through normal heating operation (3) The relative humidity may actually be low.

If a configuration is adopted in which the humidifier is controlled only by relative humidity, (1) there will be variations in the set value due to the relative humidity distribution (2) variations in the humidity sensor, temperature characteristics, aging deterioration, foreign matter adhesion, etc. will be taken into consideration. This results in large variations in settings (3) When the humidity sensor fails, problems occur because there is no guaranteed function.

Therefore, in the present invention, all of the above humidifier ON conditions are
The AND condition was used to prevent excessive humidification and ensure an appropriate amount of humidification.

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 conjunction with air conditioning conditions, it is possible to always maintain a moderate relative humidity. It is possible to minimize condensation on the wall when the heating operation is stopped.

In addition, it is possible to minimize the effects of variations in humidity sensors due to various causes, and in conjunction with temperature control in air conditioners, it greatly contributes to the realization of ideal air conditioning. Since the humidification operation stops when the lamp is turned off, there is no possibility of excessive humidification.

Furthermore, moderate humidification increases the feeling of heating,
Conversely, it becomes possible to set the room temperature to a low level, contributing to energy saving.

Further, the present invention provides, in the second condition section for determining the ON state of the thermostat for compressor operation,
Since the room temperature setting unit and the room temperature sensor that determine the ON state of the thermostat are both installed indoors, we have to install a signal line that connects the indoors and outdoors, so that we can directly know the operating status from the compressor located outdoors. No configuration is required and the configuration is not complicated.

In addition, in the present invention, even if the compressor is unavoidably temporarily stopped to protect the compressor, the temperature detected by the room temperature sensor is lower than the set temperature in the room temperature setting section, and the thermostat is not turned on. If the second condition unit determines that this is the case, it predicts that the room temperature will increase and the relative humidity decreases, and continues to operate the humidifier, quickly achieving comfortable air conditioning conditions. Is possible.
