Heat-pump water heater of high-efficiency triple co-generation air conditioner

Abstract

The invention discloses a heat-pump water heater of a high-efficiency triple co-generation air conditioner. The heat-pump water heater comprises a compressor (1), a water condenser (2), a four-way valve (3), an indoor heat exchanger (4), a throttling device (5), an outdoor heat exchanger (6) and an electric control device and the like, wherein an air outlet of the four-way valve (3) is connected with an air suction port of the compressor (1); an inlet of the outdoor heat exchanger (6) is connected with a gating port of the four-way valve (3), and an outlet of the outdoor heat exchanger (6) is connected with the throttling device (5); the heat-pump water heater also comprises a refrigerant output port (8), a refrigerant input port (9), an air-conditioner output port (10) and an air-conditioner input port (11); the air-conditioner output port (10) is connected with another gating port of the four-way valve (3); and the air-conditioner input port (11) is connected with the throttling device (5). The heat-pump water heater is characterized in that an air exhaust port of the compressor (1) is communicated with an air inlet of the four-way valve (3); the refrigerant output port (8) is connected with the air outlet of the compressor (1); and the refrigerant input port (9) is connected with the throttling device (5). The heat-pump water heater is high-efficiency and energy-saving, is multipurpose, simple in structure and control flow and extremely high in cost performance, and is suitable for being popularized and applied in a large range.

Description

Technical field [0001] The invention relates to a heat pump hot water air-conditioning system, in particular to a high-efficiency triple air-conditioning heat pump water heater, which belongs to the technical field of heat pump applications. Background technique [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 high-end heat pump water heaters when they work in summer is often not easy to be utilized. The working principle of the heat...

AI Technical Summary

Problems solved by technology

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 repeatedly configure two sets of heat pumps or refrigeration devices, which doubles user investment costs and energy use costs.

The existing technology also combines the two into one, but its composition structure and control process are generally more complicated. For example, the water condenser is connected in series between the outlet of the compressor and the inlet of the four-way valve. This mode has a low heat recovery rate. , and it is difficult for the system to return oil, and the work efficiency is not high; there are also a three-way valve or two solenoid valves connected to the four-way valve inlet and the water condenser refrigerant inlet respectively after passing through the outlet of the compressor. The control of this mode is complicated, the amount of refrigerant is not easy to adjust, but the failure rate is high, and maintenance is difficult, so it is not suitable for large-scale mass promotion and application
