[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: the refrigerant is compressed by the compressor into a high-temperature and high-pressure refrigerant that enters the water condenser and is absorbed by the water and condensed into medium-temperature and medium-pressure. The refrigerant is then decompressed by the throttling device into a low-temperature and low-pressure refrigerant, then flows into the evaporator to absorb heat energy, and finally returns to the compressor to complete the cycle

When the water temperature in the water condenser is low or high, it is easy to cause the system refrigerant return pressure to be too low, the amount of return gas and oil return is too small or the exhaust pressure is too high, the condensation temperature is too high, and the refrigerant evaporates and absorbs. Problems such as low heat capacity have seriously affected the normal performance of the heat pump water heater, and the life of the compressor has been greatly attenuated. Therefore, although the heat pump water heater has many advantages, it also has the above-mentioned fatal However, its actual use effect and actual service life are not fully satisfactory, and its structure is relatively complicated and difficult to match in actual design and manufacture, which also greatly limits the popularization and application of this new generation of energy-saving and environmentally friendly products.

To sum up, the air conditioners and heat pump water heaters in the prior art have relatively single functions and unsatisfactory performance. When people need both air conditioners and hot water, they need to configure two sets of heat pump devices repeatedly, which doubles the user investment cost and energy consumption. cost
