Air conditioning system

Abstract

To provide an air conditioning system which can reduce a power consumption amount with a simple configuration.SOLUTION: An air conditioning system 1 for a facility having a common space 2 communicatable with an outer space, and a private room space 3 communicatable with the common space 2, includes: a common air conditioning device 5 for performing cooling air conditioning in the common space 2; a private room air conditioning device 6 for performing cooling air conditioning of the private room space 3; and a private room temperature controller 6r for setting a cooling air conditioning temperature of the private room air conditioning device 6. A common lower limit temperature which is a lower limit of a cooling air conditioning temperature of the common air conditioning device 5 is lower than a private room lower limit temperature which is a lower limit of the cooling air conditioning temperature of the private room air conditioning device 6. Further, a display of a cooling setting temperature of the private room temperature controller 6r can be set to the common lower limit temperature. This allows the private room lower limit temperature to be set higher than the common lower limit temperature, and thus a cooling temperature of the private room space 3 is restricted. This can suppress an excessive cooling state in the private room space 3, thus reducing a power consumption amount with a simple configuration.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present disclosure relates to an air conditioning system, and more particularly to an air conditioning system for a facility having a shared space and private spaces. [Background technology]

[0002] Karaoke facilities and the like have traditionally been known to have a configuration that includes a shared space and private spaces (hereinafter, such facilities may be referred to as short-term use facilities. Note that short-term use facilities refer to facilities where the same user continuously uses a private space for less than one day.). Here, the common space is a space that can be shared by users and can communicate with the outside world. In addition, the private rooms are spaces that can be used individually by users and can be connected to the common space.

[0003] In such short-term use facilities, it is common for the private rooms and common spaces to be individually air-conditioned so that each user can achieve their preferred indoor temperature in the private rooms (see, for example, Patent Document 1).

[0004] Patent Document 1 discloses the configuration of an air conditioning system that adjusts the temperature of a buffer space (shared space) so as to reduce total power consumption. However, the air conditioning system in Patent Document 1 has a complex configuration, and is designed to be suitable for long-term use facilities (where the same user continuously uses a private room for a period of one day or more) that operate in a steady state, and is not suitable for short-term use facilities where users change frequently.

[0005] That is, in short-term use facilities, there is variation in the frequency of use of private rooms, and it is often the case that users change within a short period of time before the indoor temperature state of the private rooms reaches a steady state. In other words, in short-term use facilities, there is a risk that even if the air-conditioning temperature of the common space is used as a variable, the appropriate total power consumption will not be output (the result will be a collection of transient and transitional data with large variations, and the total power consumption of each private space will be output, which is not dependent on the temperature variable of the common space).

[0006] Furthermore, since temperature adjustment in the private room is left to the user, and no electricity charges are collected for increased power consumption, some users may deliberately set temperatures that result in unnecessary excessive power consumption (lower limit temperature when cooling, upper limit temperature when heating). As a result, when the absolute value of the correlation coefficient between the temperature and power consumption in the shared space is small, such as in short-term use facilities, it becomes difficult to suppress power consumption by adjusting the temperature in the shared space.

[0007] Furthermore, in recent years, there have been frequent occurrences of power supply shortages in summer and winter, when power consumption peaks, with power demand approaching power supply, making the need to curb power consumption more important than ever before.

[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-249460 Summary of the Invention [Problem to be solved by the invention]

[0009] The present disclosure has been made to solve the above problems, and its purpose is to provide an air conditioning system that has a simpler configuration and can reduce power consumption. [Means for solving the problem]

[0010] According to a first aspect of the present disclosure, the air conditioning system is an air conditioning system for a facility having a common space that can communicate with the outside space and a private space that can communicate with the common space, and is equipped with a common air conditioning device that cools and conditions the common space, a private room air conditioning device that cools and conditions the private room space, and a private room temperature controller that sets the cooling and conditioning temperature of the private room air conditioning device.

[0011] The common lower limit temperature, which is the lower limit of the cooling air conditioning temperature of the common air conditioner, is lower than the private room lower limit temperature, which is the lower limit of the cooling air conditioning temperature of the private room air conditioner. Furthermore, the cooling setting temperature of the individual room temperature controller can be displayed up to the common lower limit temperature.

[0012] As a result, the individual room lower limit temperature is set higher than the common lower limit temperature, so the cooling and air-conditioning temperature in the individual room space is limited. This prevents excessive cooling of the private room space, and reduces power consumption with a simpler configuration.

[0013] The common lower limit temperature is set lower than the individual room lower limit temperature because the common space is a space that can communicate with the outside world, and there is direct disturbance due to communication with the outside world, making it necessary to adjust the temperature over a wider range.

[0014] In addition, the cooling setting temperature of the individual room temperature controller can be displayed up to the common lower limit temperature. This allows the display of the cooling setting temperature of the private room temperature controller to show a value below the private room lower limit temperature. Therefore, the placebo effect can reduce the subjective sensible temperature without increasing power consumption.

[0015] In addition, by displaying the cooling setting temperature of the private room temperature controller up to the common lower limit temperature, the configuration of the private room temperature controller and the common temperature controller that sets the cooling air conditioning temperature of the common air conditioner can be made common. This allows the number of different types of components in the air conditioning system to be reduced, further simplifying the configuration of the air conditioning system.

[0016] According to a second aspect of the present disclosure, the air conditioning system is an air conditioning system for a facility having a common space that can communicate with the outside space and a private space that can communicate with the common space, and is equipped with a common air conditioning device that heats and conditions the common space, a private room air conditioning device that heats and conditions the private room space, and a private room temperature controller that sets the heating and conditioning temperature of the private room air conditioning device.

[0017] The common upper limit temperature, which is the upper limit of the heating and air-conditioning temperature of the common air conditioner, is higher than the private upper limit temperature, which is the upper limit of the heating and air-conditioning temperature of the private room air conditioner. Furthermore, the heating setting temperature of the individual room temperature controller can be displayed up to the common upper limit temperature.

[0018] As a result, the private room upper limit temperature is set lower than the common upper limit temperature, so the heating and air conditioning temperature in the private room space is limited. This prevents excessive heating of the private rooms, and reduces power consumption with a simpler configuration.

[0019] The common upper limit temperature is set higher than the individual room upper limit temperature because the common space is a space that can communicate with the outside world, and there is direct disturbance due to communication with the outside world, making it necessary to adjust the temperature over a wider range.

[0020] In addition, the heating setting temperature of the individual room temperature controller can be displayed up to the common upper limit temperature. This allows the display of the heating set temperature of the private room temperature controller to show a value that exceeds the private room upper limit temperature. Therefore, the placebo effect can increase the subjective sensible temperature without increasing power consumption.

[0021] In addition, by limiting the display of the heating setting temperature of the private room temperature controller to the common upper limit temperature, the configuration of the private room temperature controller and the common temperature controller that sets the heating and air conditioning temperature of the common air conditioner can be made common. This allows the number of different types of components in the air conditioning system to be reduced, further simplifying the configuration of the air conditioning system. [Brief explanation of the drawings]

[0022] [Figure 1] FIG. 1 is an explanatory diagram of an air conditioning system (embodiment); DETAILED DESCRIPTION OF THE INVENTION

[0023] Hereinafter, modes for carrying out the present disclosure will be described based on examples. It should be noted that the following examples disclose specific examples, and it goes without saying that the present disclosure is not limited to the following examples. [Example]

[0024] [Configuration of the Example] The configuration of an air conditioning system 1 according to the embodiment will be described with reference to FIG. The air conditioning system 1 is an air conditioning system for a short-term use facility such as a karaoke facility that has a common space 2 that can communicate with the outside world and a private space 3 that can communicate with the common space 2.

[0025] The air conditioning system 1 includes a shared air conditioner 5 that performs heating and cooling air conditioning in the shared space 2, a private room air conditioner 6 that performs heating and cooling air conditioning in the private room space 3, and a private room temperature controller 6r that sets the heating and cooling air conditioning temperature of the private room air conditioner 6. The cooling and heating temperature of the common air conditioner 5 is controlled by a common temperature controller 5r.

[0026] Here, the air conditioning temperature setting of the common air conditioner 5 is performed by the facility manager using a common temperature controller 5r. On the other hand, the air conditioning temperature setting of the private room air conditioner 6 is set by the user using the private room temperature controller 6r.

[0027] In addition, the common lower limit temperature, which is the lower limit of the cooling air conditioning temperature of the common air conditioner 5, is set lower than the private room lower limit temperature, which is the lower limit of the cooling air conditioning temperature of the private room air conditioner 6. Furthermore, the common upper limit temperature, which is the upper limit of the heating and air-conditioning temperature of the common air conditioner 5, is set higher than the private room upper limit temperature, which is the upper limit of the heating and air-conditioning temperature of the private room air conditioner 6.

[0028] The upper and lower limit temperatures at which the common air conditioner 5 can perform air conditioning may be limited by the common air conditioner 5 side or by the common temperature controller 5r side. Similarly, the upper and lower limit temperatures at which the private room air conditioner 6 can perform air conditioning may be limited by the private room air conditioner 6 side or by the private room temperature controller 6r side.

[0029] In the embodiment, the upper and lower limit temperatures of the common air conditioner 5 are limited by the common air conditioner 5 side, and the upper and lower limit temperatures of the private room air conditioner 6 are limited by the private room air conditioner 6 side. That is, the common air conditioner 5 and the private room air conditioner 6 are configured to perform air conditioning operation within the upper and lower limit temperature ranges regardless of the input set temperatures to the common temperature controller 5r and the private room temperature controller 6r. In the embodiment, the lower limit temperature (common lower limit temperature) of the common air conditioner 5 is 20°C, and the upper limit temperature (common upper limit temperature) is 28°C, while the lower limit temperature (private room lower limit temperature) of the private room air conditioner 6 is 22°C, and the upper limit temperature (private room upper limit temperature) is 26°C.

[0030] In addition, the cooling setting temperature of the private room temperature controller 6r can be displayed up to the common lower limit temperature. Similarly, the heating setting temperature of the private room temperature controller 6r can be displayed up to the common upper limit temperature.

[0031] That is, in the embodiment, the private room temperature controller 6r has a settable temperature display range of 20°C to 28°C, even though the temperature range that the private room air conditioner 6 can condition is 22°C to 26°C. The temperature range that can be controlled by the shared air conditioner 5 is 20°C to 28°C, and the settable temperature display range of the shared temperature controller 5r is 20°C to 28°C. Therefore, the settable temperature display range for both the common temperature controller 5r and the individual room temperature controller 6r is 20°C to 28°C.

[0032] [Effects of the Example] In the air conditioning system 1, the common lower limit temperature, which is the lower limit of the cooling air conditioning temperature of the common air conditioner 5, is lower than the private lower limit temperature, which is the lower limit of the cooling air conditioning temperature of the private air conditioner 6. As a result, the private room lower limit temperature is set higher than the common lower limit temperature, so the cooling air conditioning temperature in private room space 3 is limited. This prevents excessive cooling of the private space 3, and reduces power consumption with a simpler configuration.

[0033] The common lower limit temperature is set lower than the individual room lower limit temperature because the common space 2 is a space that can communicate with the outside world, and there is direct disturbance due to communication with the outside world, making it necessary to adjust the temperature over a wider range. In other words, the private space 3 is only connected to the common space 2 where disturbances are suppressed, and is less directly affected by disturbances in the outside space, so there is little problem even if the private lower limit temperature is set higher than the common lower limit temperature.

[0034] In the air conditioning system 1, the common upper limit temperature, which is the upper limit of the heating and air conditioning temperature of the common air conditioner 5, is higher than the private upper limit temperature, which is the upper limit of the heating and air conditioning temperature of the private room air conditioner 6. As a result, the private room upper limit temperature is set lower than the common upper limit temperature, so the heating and air conditioning temperature in the private room space is limited. This prevents the private space 3 from being excessively heated, and reduces power consumption with a simpler configuration.

[0035] The common upper limit temperature is set higher than the individual room upper limit temperature because the common space 2 is a part that can communicate with the outside space, and there is a direct disturbance due to communication with the outside space, so adjustment over a wider temperature range is required. In other words, the private space 3 is only connected to the common space 2 where disturbances are suppressed, and is less directly affected by disturbances in the outside space, so there is little problem even if the private space upper limit temperature is set lower than the common space upper limit temperature.

[0036] The effect of reducing the amount of power consumption is more pronounced when there are multiple private rooms 3. Furthermore, in the embodiment, the air conditioning system 1 is for short-term use facilities, but it goes without saying that it is also effective for long-term use facilities.

[0037] In addition, the cooling setting temperature of the private room temperature controller 6r can be displayed up to the common lower limit temperature. As a result, the cooling setting temperature display of the private room temperature controller 6r can indicate a value below the private room lower limit temperature. Therefore, the placebo effect can reduce the subjective sensible temperature without increasing power consumption.

[0038] Furthermore, by limiting the display of the cooling setting temperature of the private room temperature controller 6r to the common lower limit temperature, the private room temperature controller 6r and the common temperature controller 5r can be configured in a common manner. This allows the number of different types of components of the air conditioning system 1 to be reduced, and the configuration of the air conditioning system 1 to be simplified.

[0039] In addition, the heating setting temperature of the private room temperature controller 6r can be displayed up to the common upper limit temperature. This allows the display of the heating set temperature of the private room temperature controller 6r to show a value that exceeds the private room upper limit temperature. Therefore, the placebo effect can increase the subjective sensible temperature without increasing power consumption.

[0040] Furthermore, by limiting the display of the heating setting temperature of the private room temperature controller 6r to the common upper limit temperature, the private room temperature controller 6r and the common temperature controller 5r can be configured in a common manner. This allows the number of different types of components of the air conditioning system 1 to be reduced, and the configuration of the air conditioning system 1 to be simplified.

[0041] In addition, in the air conditioning system 1, the difference between the common lower limit temperature and the private room lower limit temperature is 2°C. Furthermore, in the air conditioning system 1, the difference between the common upper limit temperature and the private room upper limit temperature is 2°C.

[0042] It is generally said that a wind speed of 1 m / s will cause the perceived temperature to drop by 1°C. The speed of the conditioned air changes depending on the distance from the air conditioning system, so the perceived temperature also changes. For this reason, it is unlikely that a difference of around 2°C between the displayed temperature and the air-conditioned temperature will cause any discomfort. A wind speed of 2 m / s, which corresponds to a perceived temperature difference of 2°C, is equivalent to the gentle breeze produced by a typical small electric fan.

[0043] Therefore, if the difference between the common upper and lower limit temperatures and the individual upper and lower limit temperatures is 2°C, in other words, if the difference between the heating and cooling setting temperature displayed on the individual temperature controller 6r in the individual space 3 and the air conditioning temperature in the individual space 3 is approximately 2°C, it is unlikely that there will be any sense of incongruity between the displayed temperature and the actual air conditioning temperature.

[0044] [Variations] The present invention can be modified in various ways without departing from the spirit of the invention. In the embodiment, the individual room temperature controller 6r and the common temperature controller 5r have the same configuration, but a configuration using a temperature controller more suitable for each air conditioner may also be used. This allows more detailed settings to be made for each of the shared air conditioner 5 and the private room air conditioner 6. [Explanation of symbols]
