Sustav upravljanja grijanjem i više{0}}linijski-sustav klimatizacije koji sadrže isti način proizvodnje

1. Ovaj korisni model odnosi se na područje tehnologije klimatizacije, posebno na sustav upravljanja grijanjem i više{1}}linijski klimatizacijski sustav koji ih sadrži.

Pozadinska tehnika:

2. Trenutno izrazito hladne regije, hladne regije i vruće ljetne i hladne zimske regije čine više od 70 posto globalnog područja. Ove regije imaju veliku potražnju za grijanjem zimi, a više-sustavi čine više od 75 posto tržišta potražnje za grijanjem i imaju ogromno tržište.

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.
