Problems solved by technology

There is a big difference in the utilization rate of tourist buildings in winter and summer. In these areas, the temperature in summer is generally low, and air conditioning is not needed. However, in winter, it is very cold and the heating load is large.
This has resulted in the energy-saving paradox that more people consume less energy in summer, and less people consume more energy in winter
[0003] At present, due to the restriction of energy-saving regulations, the insulation of buildings in severe cold areas is relatively good. However, for buildings such as hotels with low occupancy rates, most of the rooms are not put into use in winter. In this case, the enclosure No matter how good the thermal insulation of the structure is, it doesn't make much sense, but it causes a lot of waste of construction resources

Embodiment 1

[0062] for existing buildings

[0063] 1. Conduct research and analysis on the situation of the building

[0064] The research content includes the thermal parameters of the building envelope, the meteorological parameters of the building location, the annual utilization rate of the building, and the current energy consumption of the building (including water consumption, electricity consumption, and heating consumption).

[0065] 2. Analyze the usage of the building

[0066] Mainly analyze the usage difference between winter and summer based on the usage rate in recent years, and approximate the usage rate in winter according to the usage rate and changes in recent years.

[0067] Building utilization rate = Max(λ 1 ,λ 2 ,λ 3 ...λ n )

[0068] 3. Zoning of buildings based on calculated winter occupancy

[0069] Based on the usage rate in winter, the building is divided into two parts: one is an area that is used all year round; the other is an area that is only used in...

Embodiment 2

[0077] for new construction

[0078] 1. Investigate local changes in the annual tourist flow and the annual use of similar buildings

[0079] Investigate the changes in the local annual tourist flow and the annual use of similar buildings. The utilization rate of tourist buildings is closely related to the change in local tourist flow. At the same time, according to the use objects and levels of the building and the year-round use of similar buildings, the winter and summer use of the building is approximately estimated. Building utilization rate = Max(λ 1 ,λ 2 ,λ 3 ...λ n )

[0080] 2. Zoning or segmenting the building based on calculated winter occupancy

[0081] Based on the usage rate in winter, the building is divided into two parts: one is an area that is used all year round; the other is an area that is only used in summer. The area used throughout the year should meet the utilization rate in winter, and a certain margin should be left according to the changes in...

Embodiment 3

[0089] new building

[0090] 1. Building overview

[0091] The hotel is located in a tourist city on the Qinghai-Tibet Plateau, which belongs to the severe cold area C, with a total construction area of ​​10640m2 2 , a total of 7 floors, of which 1 floor is the hotel lobby and commercial rooms, the 2nd to 6th floors of the hotel are guest rooms, and the 7th floor is the restaurant (boxes and banquet halls). The total heating area is 10013m 2 .

[0092] 2. Usage calculation

[0093] Image 6 It is the occupancy rate of a local hotel of the same type and grade in the previous year. The heating season runs from October to April.

[0094] 3. Partition selection

[0095] Based on hotel occupancy rates, building occupancy during the heating season is roughly 41%. Combined with the hotel's architectural features and functional zoning, the building is zoning. The following zoning methods are provided below:

[0096] As shown in the figure below, the building is partitioned,...

Abstract

The invention discloses a winter heating method for a building. The method comprises the steps that setting a total energy consumption value of the building in a full heating mode in winter as Q1; obtaining a usage rate of the building, and giving a heating mode of the building through the usage rate, wherein the heating mode comprises at least more than one heating mode, and the total energy consumption value Q2 under the heating mode is less than or equal to Q1; dynamically associating the total energy consumption value Q1 or Q2 with an original indoor temperature of the building, wherein when the original indoor temperature is high, the total energy consumption value of the external heating mode is less than the total energy consumption value of the external heating mode when the original indoor temperature is low. The method disclosed by the invention is mainly combined with the structure of the building, the cost is reduced, and the energy utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of heating, and specifically relates to a method for heating buildings in winter, which is mainly used for tourist buildings in the western plateau region. Background technique [0002] Summer is the peak season for tourism in tourist cities in the severe cold regions of the western plateau, and the number of tourists in winter is quite different from that in summer. The utilization rate of tourist buildings in winter and summer is very different. In these areas, the temperature in summer is generally low, and air conditioning is not needed. However, in winter, it is very cold and the heating load is large. This has resulted in the energy-saving paradox that more people consume less energy in summer, and less people consume more energy in winter. [0003] At present, due to the restriction of energy-saving regulations, the insulation of buildings in severe cold areas is relatively good. However, for buildin...
