An end-point air conditioning system for zero-energy modular customized box-type prefabricated houses

Abstract

The invention discloses a zero-energy modular custom-made box-type prefab end-point air conditioning system, which includes several box-type prefabricated houses. An air-conditioning system using solar energy as a power source is installed on the roof of the box-type prefabricated house. The main air supply pipe and the main return air pipe connected to the air conditioning system are pierced. The main air supply pipe and the main return air pipe traverse all the box-type prefabricated houses, and their ends are closed. There is a return air outlet in the box-type prefabricated house And several air supply outlets, the return air outlet is located under the main air return pipe and connected to the main air return pipe through the secondary dry air pipe, the air supply port is correspondingly located above the workstation and communicated with the main air supply pipe through the secondary dry air pipe, And the end of the secondary dry air pipe connected with the air outlet extends into the box-type board room and is installed with a telescopic section. The invention utilizes the solar energy function, and employees can determine the air supply position and air volume according to their actual needs, and realize the purpose of energy saving and emission reduction while providing a more comfortable office and living environment through the air-conditioning control mode of point cooling or point heating.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a zero-energy-consumption modular customized box-type panel house end-point air conditioning system. Background technique [0002] In order to reduce construction costs, the construction industry generally uses box-type prefabricated houses with overall planning, convenient installation and economical benefits as temporary office and living places. The box-type prefabricated houses can increase or decrease the number of occupants and office rooms according to the construction progress plan on site, which is very flexible. . However, its thermal insulation performance is low, and the heat transfer coefficient of external walls, doors, windows and roofs is much higher than that of ordinary concrete houses. The serious energy waste caused is obvious to all: (1) In box-type prefabricated houses, it takes a long time to use single air conditioners. It is even more difficult to a...

Problems solved by technology

However, its thermal insulation performance is low, and the heat transfer coefficient of exterior walls, doors, windows, and roofs is much higher than that of ordinary concrete houses, causing serious energy waste. To achieve a comfortable temperature for the body, coupled with construction personnel entering and leaving between the office and the construction site, frequently turning on and off the air conditioner, it is even more difficult to achieve a comfortable office temperature

(2) When ordinary air conditioners are used on the first and second floors of the office area in winter, due to the high heat transfer coefficient of the roof on the first floor, it often results The office staff in the district feel cold, and the office staff in the second-floor office area feel comfortable; during 10:00-16:00, due to the high solar heat radiation coefficient and the high heat transfer coefficient of the second-floor roof, the office staff in the first-floor office area feel comfortable. In the first-floor office area, the office staff will still feel dry and hot when the air conditioner is turned off; in the living area, due to the large temperature difference between inside and outside in the second half of the night, the comfortable sleeping temperature at night will not be able to satisfy the comfortable temperature in the second half of the night, and they often wake up from freezing in the second half of the night

(3) In order to improve the office and living environment, each office and living room using box-type prefabricated houses uses one air conditioner for each room, which causes serious waste of resources, but still cannot completely improve the office and living environment of construction workers
