High-efficiency heat pump hot-water air conditioner

Abstract

The invention relates to a high efficiency heat pump hot water air conditioner, belongs to the heat pump applied technology field, mainly comprising a compressor (1), a gate valve (2), a water condenser (3), an indoor heat exchanger (4), a throttling device (5), an outdoor heat exchanger (6) and a reversing arrangement (7). The outdoor heat exchanger (6) and the reversing arrangement (7) form a refrigerant closed cycle system which is controlled by an electric control device (8). The system is characterized in that the refrigerant outlet of the water condenser (3) is at least separated into two ways by a gate device (9). One way is connected with the throttling device (5), and at least one way is connected with the inlet of high pressure refrigerant of the indoor heat exchanger (4) or the outdoor heat exchanger (6) or at least two other ways are connected with the inlet of high pressure refrigerant of the indoor heat exchanger (4) or the outdoor heat exchanger (6). The high efficiency heat pump hot water air conditioner can realize multiple effects with one device, can supply air conditioning and hot water with high efficiency and energy saving. The speed of the hot water is speed, the performance is stable and the service life is long.

Description

Technical field [0001] The invention relates to a heat pump hot water air conditioner system, in particular to a high-efficiency heat pump hot water air conditioner, which belongs to the technical field of heat pump applications.

[0002] Existing heat pump air conditioners have a single function, and generally can only be used to adjust air performance parameters and discharge hot air to the outside when cooling in summer, which not only wastes a lot of heat energy, but also affects the external environment, resulting in urban heat island effect, not It is beneficial to environmental protection, and its refrigeration efficiency is low; heat pump water heater has excellent performances such as high thermal efficiency, energy saving, safety and environmental protection. The large amount of cooling capacity generated by heat pump water heaters in summer is often not easy to be utilized. The working principle is that the refrigerant is compressed by the compressor into high temperature and high pressure refrigerant. After entering the water condenser, the heat is absorbed by the water and condensed into medium temperature and medium pressure refrigeration. Then, it is decompressed into a low-temperature and low-pressure refrigerant by the throttling device, and then flows into the evaporator to absorb heat energy, and finally returns to the compressor to complete the cycle.
