Embodiment Construction

[0009] Referring to the accompanying drawings, the present invention includes a water source heat pump 1 and an air source carbon dioxide heat pump 2. The water source heat pump 1 is composed of a compressor A1, a condenser A2, an expansion valve A3 and an evaporator A4 and communicated through a water pipe 3. The air source carbon dioxide heat pump 2 is mainly composed of The compressor B1, the gas cooler B2, the intermediate heat exchanger B3, the expansion valve B4, the evaporator B5, and the gas-liquid separator B6 are composed and communicated through the water pipe 3, and a part of the hot water backwater flows through the condenser A2 of the water source heat pump 1. After being heated to the set temperature, it is sent out, and a part of it flows through the evaporator A4 of the water source heat pump 1. After the heat is absorbed, the temperature drops and enters the gas cooler B2 of the air source carbon dioxide heat pump 2. After being heated to the set temperature, i...

Abstract

The invention relates to a double-source heat pump device capable of realizing the heating function, which adopts the technical scheme that the double-source heat pump device capable of realizing the heating function comprises a water source heat pump and an air source carbon dioxide heat pump. The water source heat pump comprises a compressor, a condenser, an expansion valve and an evaporator which are all communicated by water pipes; and the air source carbon dioxide heat pump mainly comprises a compressor, a gas cooler, a middle heat exchanger, an expansion valve, an evaporator and a gas-liquid separator which are all communicated by water pipes. Part hot backwater is heated to the set temperature by the condenser of the water source heat pump and is then delivered; and the heat of part hot backwater is absorbed by the evaporator of the water source heat pump, and the part hot backwater with lowered temperature enters the gas cooler of the air source carbon dioxide heat pump to be heated to the set temperature and is then sent out, wherein the refrigerating fluid of the air source carbon dioxide heat pump is carbon dioxide. The invention is environment-friendly without pollution, and has high heating speed, safety and reliability.

Description

1. Technical field: [0001] The invention relates to a heating device, in particular to a dual-source heat pump device capable of realizing the heating function. 2. Background technology: [0002] In recent years, the natural working substance carbon dioxide has been paid more and more attention by the refrigeration industry because of its non-toxic, non-flammable, ozone destruction index GDP of 0, and global warming potential GWP of 1. One of the most potential natural working fluids in quality substitution. With its unique performance, the carbon dioxide heat pump system can easily produce hot water above 60°C. The good characteristics of the carbon dioxide heat pump system make it possible to achieve a high energy efficiency ratio and hot water temperature even in a low temperature environment. However, it also has its limitations. The critical temperature is 31°C. When the inlet water temperature is higher, such as greater than 35°C, the system performance will drop gre...
