Problems solved by technology

[0035] However, the comfort felt by people is not only dependent on the thermal environment, but also largely depends on the humidity, so the control of the humidity environment is also desired, but since many buildings do not have a humidity measuring device, it is impossible to control the humidity environment. the problem of control

Embodiment Construction

[0046]

[0047] refer to figure 1 , the configuration of the humidity estimation device 10 according to one embodiment of the present invention will be described.

[0048] The humidity estimating device 10 in this embodiment is installed in an air conditioner for air-conditioning the interior of a building, and has an intake air flow estimating unit 11, an intake air absolute humidity estimating unit 12, an indoor water vapor generation amount estimating unit 13, and Indoor absolute humidity estimation unit 14 . In this embodiment, it is assumed that a plurality (n units) of air conditioners 1 to n are installed indoors of an air-conditioning control target.

[0049]The intake air flow rate estimating unit 11 acquires the rotational speed of the intake fan under control from a DDC (Direct Digital Controller, not shown) in the air conditioners 1 to n as operating control information of the intake fan, and uses the The rotational speed of the intake fan and the preset fan di...

Abstract

A humidity estimation device connected with an air-conditioner includes a charge airflow rate estimation (CARE) unit, a charge air absolute humidity estimation (CAAHE) unit, an indoor generated vapor amount estimation (IGVAE) unit, and an indoor absolute humidity estimation (IAHE) unit. The CARE unit calculates an estimated charge airflow rate (ECAR) of the air-conditioner based on operation control information of the charge fan and a preset fan differential pressure. The CAAHE unit calculates an estimated charge air absolute humidity (ECAAH) of the air-conditioner based on a charge air temperature and a preset charge air relative humidity. The IGVAE unit calculates an estimated indoor generated vapor amount (EIGVA) based on an indoor temperature, the number of persons in the room and activity index values of the persons. The IAHE unit calculates an estimated absolute humidity in the room based on the ECAR, the ECAAH and the EIGVA.

Description

technical field [0001] The present invention relates to a humidity estimating device and a humidity estimating method for estimating an indoor humidity value used for calculating an air-conditioning setting value in an air conditioner for indoor air-conditioning control of buildings such as buildings and hospitals. Background technique [0002] In general, energy consumption related to air conditioning accounts for about half of the energy consumption of the entire building equipment, and the promotion of energy-saving air-conditioning controls contributes significantly to the energy saving of the entire building equipment. [0003] On the other hand, in the interior of an office building or the like, which is a comfortable space, it is required to satisfy the thermal sensation of occupants, that is, so-called comfort. Securing the comfort and saving energy are two opposite aspects, but by suppressing excessive energy consumption beyond the comfortable range of occupants, en...
