Radiation heat exchange air-conditioning method of ceiling carrying energy by virtue of circulation air

Abstract

The invention discloses a radiation heat exchange air-conditioning method of ceiling carrying energy by virtue of circulation air. The method is as follows: a metal ceiling is utilized to divide a room into an upper buffer energy storage region and a lower air-conditioning region; the cold and warm air of an air conditioner is not directly fed to the air-conditioning region and fed to the buffer energy storage region at which most air transfers cold and heat energies to the metal ceiling in a heat convection mode and then directly returns back to the air conditioner; a small part of air permeates to the air-conditioning region through micropores on the metal ceiling and returns back to the air conditioner by the air return port after eliminating remained humidity; and the metal ceiling continuously acquires the cold and heat energies from the circulation air so as to gradually enlarge the temperature difference between the metal ceiling and the air-conditioning region, and the air conditioning is carried out on the air-conditioning region in a radiation heat exchange mode. The steps are circularly operated, thereby achieving the radiation heat exchange air-conditioning method of the ceiling carrying the energy by virtue of circulation air. The method has the advantage of energy conservation and quiet, a ceiling radiation heat exchange air conditioner also has the advantage that an air replacing air conditioner is not easy to form dew in summer; and construction cost is proper, and installation and maintenance are convenient. Thus, the method is in favor of popularization and application.

Description

technical field [0001] The invention relates to the fields of architectural decoration and air conditioning, in particular to a ceiling radiation heat exchange air conditioning method carried by circulating air. Background technique [0002] At present, there are mainly two types of air-conditioning terminals, one is the fan coil air displacement air conditioner, and the other is the floor or blooming plate radiation heat exchange air conditioner, which are described as follows: [0003] 1. At present, there are two air supply methods for air-displacement air conditioners. One is to install the air conditioner directly in the air-conditioning area, and the air supply air is blown directly to a certain direction in the air-conditioning area; the other is not to install the air conditioner in the air-conditioning area. The air-conditioning area is connected to the air-conditioning area through the air duct, and an air outlet is set in the air-conditioning area, and the air-con...

Problems solved by technology

The common features of the above two air-conditioning air supply methods are: the air-conditioning air supply is directly sent to the air-conditioning area, and the waste heat and humidity are treated through air replacement. However, because the air supply from the air conditioner is directly blown to the air conditioning area, the wind force is concentrated, the air supply noise is large, the temperature in the room is not uniform, the human body feels less comfortable, and the secondary dust caused by the air supply pollutes the environment. , affecting people's normal rest and quality of life;

[0004] 2. At present, there are two main methods of radiation heat exchange air conditioning: one is the floor radiation heat exchange air conditioner used for heating in winter; the other is to attach and install the heat exchange coil of the air conditioner circulating water system on the metal ceiling. The heat coil directly conducts heat to the ceiling radiation heat exchange air conditioner of the metal ceiling. The common characteristics of the above two heat transfer methods of the radiation heat exchange air conditioner are: the temperature in the air conditioning area is uniform, energy saving and comfort are obvious, but the heat exchange coil needs to be installed in the On the radiant heat exchange floor or ceiling, the heat is carried and transferred through the air-conditioning circulating water system, so the cross-construction or maintenance between the heat exchange coil and the heat exchange coil must be very careful, otherwise the heat exchange coil is easily damaged, causing the floor to leak. Water or ceiling leakage, due to its high cost, the problem of condensation on the radiation heat exchange plate in summer is not easy to control, and the promotion is restricted
