Five Constant Homes, providing you with a healthy and quality home that breathes

With the development of science and technology and the improvement of people's quality of life, healthy and comfortable high-tech houses are becoming a new living aspiration. If you are renovating or preparing to renovate, you must have heard of the five constant systems, which are high-comfort, low-energy home solutions that can maintain suitable temperature and humidity all year round, fresh air and cleanliness, and healthy living as a selling point.

Five Constant Systems

Constant Temperature, Humidity, Oxygen, Cleanliness and Quietness

Five Constant System adopts advanced control technology and highly efficient equipment to continuously and stably regulate indoor temperature, humidity, air quality and other parameters so that the indoor environment reaches a constant state. The living space created by Wuheng system is windless and noiseless, the temperature is constant between 20℃ and 26℃, the relative humidity is kept in the ideal range between 35% and 65%, the oxygen content is maintained at the most suitable level for human body, meanwhile, the indoor noise is lower than 30 decibels, and the air quality is fresh and natural.

Doors and windows are the top priority

To achieve such an ideal living environment, it is not enough to rely solely on the core equipment of the five constant systems. The airtightness of the building, especially the performance of the door and window system, has a crucial impact on the operation of the five constant systems. If the sealing performance of the doors and windows is not good, the haze, dust, noise and other adverse factors from the outside will easily enter the room and destroy the balance of the five constant systems.

High-quality, high-performance doors and windows have good sealing performance, which can effectively isolate external noise and pollutants, keep the room quiet and the air clean. At the same time, the excellent thermal insulation performance can reduce the burden of the five constant systems on indoor constant temperature regulation and improve energy efficiency.
