specific Embodiment approach 1

[0018] Specific implementation mode one: this implementation mode is a method for heating the spectator area of ​​an ice sports stadium, specifically carried out according to the following steps:

[0019] A notch with a width of 0.5 meters is set on the ground between the auditorium and the ice arena, and a hot air curtain is fixed in the notch; the hot air curtain adopts dual air sources; the hot air curtain is a cross-flow hot air curtain ; The air outlet temperature of the hot air curtain is 48 ° C ~ 50 ° C, the wind speed is 7 m / s ~ 10 m / s, and the nozzle air flow rate is 3870 m 3 / m·h~4000m 3 / m h; The position of the notch relative to the auditorium ensures that the temperature of the ice surface is -5~-6°C when the hot air curtain is working, the thickness of the ice is 3cm~5cm, and the temperature of the first row of auditoriums is 17 ℃~20℃.

specific Embodiment approach 2

[0020] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the hot air curtain adopts PTC heating method. Others are the same as the first embodiment.

specific Embodiment approach 3

[0021] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the temperature of the air outlet of the hot air curtain is 48°C. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a method for heating an audience area of an ice stadium, and relates to a method for heating the audience area of a stadium. The method for heating the audience area of the icestadium aims to solve the technical problem that the thermal comfort is unsatisfying in front rows of the audience area of existing ice sports stadiums because of the existence of ice surface. The method for heating the audience area of the ice stadium comprises the steps that a notch is formed in the ground between the audience area and the ice stadium, and a warm air curtain is fixedly arrangedin the notch. The method for heating the audience area of the ice stadium has the advantages that (1) the air volume is small, and the supply air height and the noise are low; (2) thermal insulationis achieved, specifically, the exchange of hot and cold air of 60%-80% of the heating area on the ice between the stadium and the audience is effectively prevented, so that the temperature change on both sides of the wind screen area is reduced; (3) heating is performed, specifically, PTC heating is used for heating part air in the front row of the audience area to enhance the thermal comfort of the nearest area to the ice stadium; and (4) dust proof is achieved, specifically, the dust from the audience area is effectively blocked into the ice stadium to affect the performance of the competition.

Description

technical field [0001] The invention relates to a method for heating the audience area of ​​a stadium. Background technique [0002] Due to the existence of the ice surface in the existing ice sports venues, the ice stadium absorbs heat, resulting in low temperature inside the venue, unstable thermal balance at the border of the audience area, and poor thermal comfort in the front row of the audience area. Contents of the invention [0003] The present invention aims to solve the technical problem of poor thermal comfort in the front row of the spectator area in existing ice sports stadiums due to the existence of the ice surface, and provides a heating method for the audience area of ​​the ice stadium. [0004] The method for heating the spectator area of ​​a kind of ice gymnasium of the present invention is carried out according to the following steps: [0005] A notch with a width of 0.5 meters is set on the ground between the auditorium and the ice arena, and a hot ai...
