Description

  The present invention relates to an air conditioning control support data generation device, an air conditioning control support data display device, and an air conditioning control support data generation method for supporting an air conditioning control operation in an office building or factory.

  In recent years, in air conditioning control in office buildings and factories, it has been required to secure a comfortable indoor thermal environment with as little energy consumption as possible.

  However, there is a trade-off between this energy saving and ensuring a comfortable indoor thermal environment. If priority is given to energy saving, the indoor thermal environment will deteriorate and there will be many complaints from residents, improving the indoor thermal environment. If the number of complaints from occupants is reduced, the energy used often increases and does not lead to energy saving.

  By the way, in such office buildings and factories, in many cases, air conditioning control is performed by an operator's operation with reference to a PMV (Predicted Mean Vote) value that is an index indicating the comfort level felt by people.

  This PMV value was proposed by Mr. Fanger. According to the comfort equation presented by Mr. Fanger, the degree of comfort is 7 levels (+3; hot, +2; warm, +1; slightly warm, 0; either Not comfortable, -1; slightly cool, -2; cool, -3; cold). When this value is 0, it is comfortable.

  PMV values are calculated not only from changes in temperature such as hot and cold, but also from an index of comfort by combining six factors: metabolism (physical activity), amount of clothing, temperature, humidity, average radiation temperature, and airflow velocity. Since it is calculated, it is possible to perform air conditioning control more suited to the human experience.

  As a technique using the PMV value, there is an air conditioning control system shown in Patent Document 1.

The air conditioning control system disclosed in Patent Document 1 calculates an average value of PMV values for each occupant and performs air conditioning control based on the average value, thereby controlling a large number of people to be comfortable. It is.
JP-A-2005-77066

  However, in the conventional air conditioning control system using the PMV value as described above, when the operator controls the air conditioning equipment by referring to the PMV value, the operator relies heavily on the intuition of the operator, and the indoor thermal environment rather than energy saving. There is a problem that energy saving effect cannot be obtained because it is often set so that complaints from occupants do not come in the priority of improving the quality of the room.

  In addition, the PMV value to be referred to is often different between the value around the sensor for measuring the indoor environment and the value at the position where the occupant is present, so that accurate air conditioning control is performed with high accuracy for the occupant. There was a problem that was difficult.

  Therefore, an object of the present invention is to provide an air conditioning control support data generation device and an air conditioning control for ensuring a comfortable indoor thermal environment with as little energy consumption as possible and supporting control operations when performing accurate air conditioning control for the occupants. An object is to provide a support data display device and an air conditioning control support data generation method.

Acquired by the data acquisition unit, the PMV value calculation unit that calculates the PMV value from the value indicating the indoor environment of the control target and the state of the occupant acquired by the data acquisition unit, and acquired by the data acquisition unit A display data generation unit that generates air-conditioning control support data indicating a ratio of the number of claims to each PMV value in the room to be controlled from the claim data and the PMV value calculated by the PMV value calculation unit; Features.

  Moreover, the air-conditioning control support data display device of the present invention includes a display unit that displays the air-conditioning control support data generated by the air-conditioning control support data generation device.

  Further, the air conditioning control support data generation method of the present invention acquires data for acquiring values indicating the indoor environment to be controlled and the state of the occupant when the complaint data regarding the complaint about the air conditioning control from the occupant is acquired. A step, a PMV value calculation step for calculating a PMV value from values indicating the indoor environment of the controlled object and the state of the occupants acquired in the data acquisition step, claim data acquired in the data acquisition step, And a display data generation step of generating air conditioning control support data indicating a ratio of the number of complaints with respect to each PMV value in the room to be controlled from the PMV value calculated in the PMV value calculation step.
