What parameters should be understood when choosing a central air-conditioning air-cooled heat pump unit

You must be familiar with central air-conditioning, but did you know that there is a unit in central air-conditioning called a cold and heat pump unit? The work of central air-conditioning is inseparable from it. Many friends may want to know the air-cooled heat pump unit of central air-conditioning. What is the basic performance, so here is the editor of okmarrs.com to introduce to you.

　　 folding heat and cold

　　 This parameter is the most critical parameter that determines the normal use of the air-cooled heat pump. It refers to the cooling capacity or heating capacity of the air-cooled heat pump unit and the inlet and outlet water temperatures under the design conditions. It can be found from the product samples provided by the relevant manufacturers. However, it is also found in the design that the sample parameters provided by some manufacturers have not been tested but copied from relevant samples of other manufacturers. This brings certain difficulties to the correct selection of designers.

Therefore, the editor of okmarts.com suggests that, if possible, the designer can obtain the variable-condition performance curve of the compressor from the compressor manufacturer according to the compressor model configured by the air-cooled heat pump of the relevant manufacturer. According to the heat pump Check the cooling capacity and heating capacity of the compressor under the design conditions of the heat pump to determine the authenticity of the parameters provided by the sample.

　　 folding COP value

　　 This value is an important parameter to determine the performance of the air-cooled heat pump. The value of its value directly affects the power consumption of the air-cooled heat pump. Therefore, the unit with a high COP value should be selected as far as possible. At present, my country's national standard is that the COP value is 2.57. The COP of most imported or joint venture brands is around 3, and the value of high-efficiency units of individual imported brands can reach 3.8.

　　 folding noise

　　 Noise is also an important parameter to measure an air-cooled heat pump unit, and it is directly related to the impact of the heat pump on the surrounding environment. Relevant domestic experts once classified the noise of various imported heat pumps into three levels based on actual engineering measurements. The first level is above 85dB, the second level is between 75-85dB, and the third level is below 75dB. We should prioritize the selection of units with noise below 80dB in the selection of engineering design.

　　Folded size

Most of the air-cooled heat pump units are arranged on the outdoor roof. When the equipment is arranged, the distance between the equipment and the surrounding wall and the distance between the equipment have clear requirements. Therefore, we must consider whether the selected equipment size is Meet the size requirements of equipment layout. Under the premise of the same performance, smaller units should be selected first to reduce the equipment footprint.

　　 folding running weight

　　As most of the air-cooled heat pump units are arranged on the roof, the load-bearing capacity of the roof must be considered when selecting the type. If necessary, the structural professional should be negotiated to enhance the load-bearing capacity of the roof. However, when selecting equipment, we should give priority to units with lighter operating weight.
