Problems solved by technology

Although triple heat pump systems have appeared in recent years, because three sets of heat exchangers are used, the hot water use time is short, and the cooling and heating time is long, resulting in the intermittent operation of the hot water exchanger in the system. The medium refrigerant is greatly affected by the ambient temperature, and the distribution balance of the refrigerant is difficult to solve. Although the liquid storage tank has been added to improve the distribution balance of the refrigerant, it still cannot completely solve the problem of the distribution balance of the refrigerant. Too much, the pressure is too high, the service life of the equipment is shortened, when high temperature hot water is needed in winter, the refrigerant is insufficient, and the energy efficiency ratio decreases

Description

technical field [0001] The invention relates to the technical field of cooling and heating, in particular to a system and method for regulating cooling, heating, and hot water. Background technique [0002] In the prior art, air conditioners are commonly used for refrigeration, various water heaters are used for hot water supply, and oil, coal, gas and electricity are used for floor heating. It was not until the emergence of heat pumps that daily cooling and heating were integrated, but hot water The system is still an independent system. [0003] After years of R&D and application practice, the heat pump industry has made great progress. However, in recent years, most companies have generally improved the matching and details of the appearance, system piping and other parts, and no major breakthroughs have been made in the heat pump structure. . Although triple heat pump systems have also appeared in recent years, because three sets of heat exchangers are used, the hot wa...
