Sistem kawalan pemanasan dan sistem penghawa dingin-berbilang talian-yang mengandungi kaedah pembuatan yang sama

1. Model utiliti ini berkaitan dengan bidang teknologi penyaman udara, khususnya sistem kawalan pemanasan dan sistem penyaman udara berbilang-baris yang mengandungi yang sama.

Teknik latar belakang:

2. Pada masa ini, kawasan yang sangat sejuk, kawasan sejuk, dan kawasan musim panas dan musim sejuk yang panas menyumbang lebih daripada 70 peratus daripada kawasan global. Wilayah ini mempunyai permintaan pemanasan yang tinggi pada musim sejuk dan sistem berbilang-talian menyumbang lebih daripada 75 peratus daripada pasaran permintaan pemanasan dan mempunyai Pasaran yang besar.

3. The current conventional multi-line air-conditioning system generally has the problem of low-temperature heating capacity attenuation, resulting in poor comfort in winter. The main reason is that the outdoor unit heat exchanger gradually frosts during the low-temperature heating process of the multi-line system, which causes the refrigerant to evaporate. Completely, the accumulation of liquid is gradually formed in the gas, causing the system's refrigerant circulation to gradually decrease, so that the heat absorption of evaporation becomes lower and lower, the heat exchange capacity of the indoor unit gradually decreases, and the frequency of defrosting increases. On the market, the method to solve the above problems is usually to add electric auxiliary heating to the indoor unit, but this scheme has a large electric auxiliary heating power and does not save energy, and is facing a situation of phasing out.
