Varmekontrolsystem og multi-klimaanlæg- med flere linier, der indeholder samme fremstillingsmetode

1. Denne brugsmodel relaterer til området for klimaanlægsteknologi, især til et varmestyringssystem og et multi-klimaanlæg, der indeholder samme.

Baggrundsteknik:

2. På nuværende tidspunkt tegner stærkt kolde regioner, kolde regioner og varme sommer- og kolde vinterregioner sig for mere end 70 procent af det globale areal. Disse regioner har høj efterspørgsel efter varme om vinteren, og systemer med flere-linjer tegner sig for mere end 75 procent af markedet for varmeefterspørgsel og har et stort marked.

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.
