Abstract

The invention relates to a multifunctional heat pump unit which uses floor radiation to heat or cool, and the unit relates to a multifunctional heat pump system which uses the floor radiation to heat or cool the room and realizes the production of domestic hot water. The unit comprises a refrigerant circulating loop, a domestic hot water loop and a cold / heat supplying loop, and can realize five running conditions: independent refrigerating, combined refrigerating and domestic hot water producing, independent heating, combined heating and domestic hot water producing and independent domestic hot water producing. The invention can constantly absorb heat from the supplied heat water when defrosting, the comfortableness of an air conditioner is greatly improved, a four-way valve does not act during the defrosting, and the stability and the reliability of the system are greatly increased.

Description

technical field [0001] The invention relates to a multi-functional heat pump system which utilizes floor radiation to supply cooling and heating indoors and simultaneously realizes domestic hot water production, and belongs to the technical field of design and manufacture of refrigeration and air-conditioning systems. Background technique [0002] The energy problem has become a global problem. With the development of the economy and the continuous improvement of people's living standards, people have higher and higher requirements for the comfort of living and working environments. The intensification of energy consumption not only accelerates the consumption of fossil energy and depletion, while increasing the pollution of the environment. As an important energy-saving technology, heat pumps have been widely used in thousands of households. At present, heat pump air conditioners in most households only realize the functions of cooling in summer and heating in winter. With ...
