• What’s Advantage of Valve Type Selection and Delay Time Setting in Wiring Centre

    When setting up the HR-02 wireless wiring centre for heat pump heating system, two critical parameters need attention: Valve Type Selection and Delay Time Setting. Proper configuration of these settings is essential for optimal system performance.

    room heating control

    1. Valve Type Selection

    The actuator type can be configured to either Normally Open (NO) or Normally Closed (NC). The choice determines how the actuators respond when the heating system is activated.

    Choosing the wrong valve type can lead to system malfunctions, such as the wiring centre failing to operate correctly. The HR-02 wiring centre allows for easy selection between NO and NC configurations, ensuring that users can adjust settings according to their specific needs without concern.

     

    2. Delay Time Setting

    The delay time setting for the pump and boiler can be adjusted between 0 to 6 minutes using a bridge jumper. This feature is crucial as it helps mitigate issues related to short cycling, where the pump and boiler frequently turn on and off in quick succession. Short cycling can lead to increased wear and tear on these components, potentially shortening their lifespan.

     

    The proper delay time can ensure the pump and boiler have adequate time to stabilize before being activated again to protect the equipment and keep the room heating control without reducing unnecessary energy consumption.

  • Floor Standing Air Conditioner Column Type V.S. Square Type, Which Option Is Best for You?

    When choosing standing air conditioners, column type and square type (traditional) are two main streams. They have clear differences in design, airflow, space occupation, suitable scenarios, and price. In case of that, an accurate model is of vital importance to the comfort and the overall beauty of the home.

     

    Column Type Standing Air Conditioner Features.

     

    1. Modern design, fashionable appearance.

    Floor standing air conditioner column type is usually adapted with a streamlined design, which makes it simple and pleasant, being more suitable for modern household styles.

     

    2. Less space occupation.

    Its bottom area is relatively small, which can make better use of space and will not look abrupt even if placed in a corner. This feature makes it very suitable for small apartments, well-decorated homes, and places with high requirements for space utilization.

     

    3. Even airflow, better comfort.

    Compared with normal standing aircon units, column air conditioners use surround three-dimensional air supply with a wider airflow angle and more even air distribution, ensuring a more stable and comfortable indoor temperature. Besides, without the feeling of strong direct airflow, the air is smoother, which is more suitable for human needs

     

    4. High EER, silent operation.

    Most of the column standing air conditioners are adapted with inverter tech, which is more efficient and energy saving compared with traditional floor standing air conditioners. And at the same time, they are more outstanding in noise control, providing a more quiet room area.

     

    5. Higher cost, suitable for high-end pursuit customers

    Column floor standing air conditioners are well improved in design, materials, and technology, so the cost will be higher than square ones. For people with sufficient budgets and the pursuit of high quality life, then, the column floor standing air conditioner is the best choice.

    Square Type Standing Air Conditioner Features.

     

    1. Traditional steady design, wide application.

    The appearance of square type floor standing air conditioners is relatively square. It is not as fresh and innovative as column ones, but it is classic. For customers who pursue applicability, it is suitable for all kinds of home styles and will never old or out of date.

     

    2. Centralized air supply, strong airflow, and fast cooling.

    One-way and small-angle swing air supply are the main methods of traditional square floor standing air conditioners. Compared with column type, the airflow is more centralized, and the cooling speed is faster. For large spaces, its powerful wind could quickly lower the indoor temperature to a comfortable level.

     

    3. Wide coverage suitable for large spaces.

    Square type floor standing air conditioners are suitable for large areas, such as living rooms, conference rooms, and shops. Its long distance air supply ability could ensure the average temperature inside the room.

     

    4. Cost-effective, cheaper price.

    Floor standing air conditioner square type is cheaper than a column one, which is suitable for customers who need a large airflow volume with a tight budget. Some high-end models are not cheaper as well, but they are cost-effective.

     

    5. More spaces occupied.

    The volume of the square standing air conditioner is large, which requires a larger space prepared for display. If the room is compact or a small house, it will occupy more space. So before we purchase a standing air conditioner, it is better to check if the display area for the indoor unit is available.

  • Chinese New Year customs

    The Spring Festival is the most solemn traditional festival in China, also known as the "Lunar New Year", which symbolizes farewell to the old and welcoming the new, as well as reunion and happiness. Here are some classic Spring Festival customs:

     

    1. Preparation beforehand

    Preparations for the Spring Festival begin in the twelfth lunar month. The 23rd or 24th day of the twelfth lunar month is the "Sacrifice to the Stove Festival". People worship the Stove King and pray for good luck in the coming year. Then there is a general cleaning to remove old dust, which means "removing the old and creating the new". Every household puts up Spring Festival couplets, window grilles and blessing characters to create a strong festive atmosphere.

     

    2. New Year’s Eve reunion

    New Year's Eve is the highlight of the Spring Festival. On this day, families gather together for New Year's Eve dinner. The fish on the table symbolizes "abundance every year" and the dumplings mean "attracting wealth and treasure". There is a tradition of staying up late on New Year's Eve. Elders tell family stories and the sound of fireworks and firecrackers not only ward off evil spirits and avoid disasters, but also express warm expectations for the New Year.

    3. New Year greetings in the first month

    On the first day of the first lunar month, people wear new clothes, pay New Year greetings, and express their best wishes to relatives and friends. Elders give "New Year's money" to their children to express their hopes for safe growth. There will also be folk performances such as dragon dance, lion dance, and stilt walking in rural areas, which are festive and lively.

     

    4. The end of the Lantern Festival

    The end of the Spring Festival is the Lantern Festival. People eat glutinous rice balls, watch lanterns, and guess lantern riddles, symbolizing a happy reunion and drawing a successful conclusion to the Spring Festival.

     

    The customs of the Spring Festival reflect the Chinese people's pursuit of family reunion, happiness and health, and are an important symbol of Chinese culture.
