How to choose the type of air energy heating unit?

The selection of air source heating units should also be considered from many aspects, one is the building heating area, providing heating for different areas of residences, what is needed is different specifications of heat pump units, to avoid energy waste, the heating area of the heat pump must be prioritized, and the choice is made according to the specific situation. The second is the heating end of the air energy heat pump, different ends have different water temperature requirements, only to determine the end, the selection of heat pump units can be more accurate. The third is to understand the insulation of the building, the thickness of the wall, the insulation of the roof, whether the glass doors and windows are double-layer design, the height of the interior, etc., will affect the insulation of the building, and all need to be added to the selection for reference.

Generally speaking, the selection of air source heating units is not an easy task, if you do have this need, you can find a professional person to choose for you, listen to the people around you say that the air has a ** selection, it is very convenient, you can go to see.

Butterfly Love Flower": Beautiful Xian'e Shengyue Palace. To the world, it is inevitable that everything will be chaotic. Song Yu's wall flows eastward. We have met in the depths of the flowers.

1. Determine and calculate the heat index and heat load according to the meteorological information of the building, the building envelope, the thermal insulation status, the characteristics of the use scene, the use habits, etc.;

2. Determine the type of air source heat pump used according to the meteorological information of the building, and select the type and quantity of the unit according to the heat load;

3. The end of the design and selection of the selling end, the design of the system form. According to the end form, the system form is missing to determine the selection of the water beard hand pump, the selection of the pipeline and the selection of other auxiliary accessories;

4. System control form and logic design.

The main differences between the selection of air source heat pump heating system and the current standard are as follows:

The performance parameters of heat pump units are different: the current standards usually require that the customized heat, rated cooling capacity, energy efficiency ratio and other parameters of heat pump units meet the national standards, while the actual selection of megamu should be comprehensively considered according to the use needs of the building and geographical and climatic conditions and other factors to ensure that the performance parameters of the heat pump unit can meet the actual needs.

Brand and model selection of heat pump unit: The current standard usually only requires the selection of heat pump units that meet national standards, and in the actual selection, it should be selected according to the brand and model of the heat pump unit, considering its stability, reliability, repair and maintenance convenience and other factors.

Matching of heat pump unit and building structure: The matching of heat pump unit and building structure needs to be considered in the actual selection, such as the size of the indoor space, pipe layout, heating area and other factors, to ensure the best operation effect of the system.

Determination of design parameters: The current standard usually only stipulates some basic design parameters, such as the amount of customized heat and rated cooling capacity of the heat pump destroying and guessing unit, etc., while more design parameters need to be determined in the actual selection, such as hot water temperature, heating and cooling ratio, unit operation mode, etc., to meet the actual use needs.

To sum up, the main difference between the selection of air source heat pump heating system and the current standard is that the actual selection needs to comprehensively consider more fiber factors, and determine more design parameters according to the actual situation to ensure that the system can meet the actual use needs.

1) The outer diameter of the ground limb is small (DN13mm);

2) The pipe spacing of the ground ant heating module should be about 100mm;

3) The thickness of the floor heating module should not be less than 30mm;

4) The length of floor heating pipe laying ranges from 80m to 100m;

5) The inlet water temperature is suitable for about 45, and the temperature difference between the supply and return water is 5.
