Problems solved by technology

As the ambient temperature gradually drops, the evaporation temperature of the system decreases, the compressor suction specific capacity increases, and the gas transmission coefficient decreases, resulting in a decrease in heating capacity, a corresponding decrease in the system energy efficiency ratio (COP), and a decrease in economy

[0021] Example

[0022] Such as figure 1 Shown is a schematic structural diagram of the ultra-low temperature air source heat pump water heater of the present invention. The heat pump water heater includes a compressor 1, a cavity 16 is provided in the middle of the compressor 1, and an air supplement port 17 is provided on one side of the compressor 1. Supplement the medium-pressure gas, increase its exhaust volume, reduce the exhaust temperature, and increase the heating capacity, so that the heat pump water heater can provide sufficient heating capacity even at low ambient temperatures. It can also avoid the compressor without air supply port when the ambient temperature is low, the circulating flow of the refrigerant is small, so that the compressor lubricating oil cannot return to the compressor 1, and the compressor 1 winding failure caused by the poor lubrication of the compressor occurs.

[0023] The heat pump water heater also includes an air supplement circuit formed by...

Abstract

The invention relates to a ultralow temperature air source heat pump hot-water machine, which comprises a compression engine(1),a air-side heat exchanger (5) and a hot-water-side heat exchanger(8) which are connected by pipeline; the compression engine(1) is internally provided with a cavity(16), one side of the compression engine(1) is provided with an air-supplement port. The heat pump hot-water machine further comprises an air-supply return circuit, a refrigerating circuit and an auxiliary air-supply return circuit. The heat pump hot-water machine can work in the ultralow temperature work environment, and has low delivery temperature, improves the conversion of thermal energy effect and the system energy efficiency ratio, and is favor of energy saving and environmental protection.

Description

technical field [0001] The invention relates to a water heater, which belongs to the field of electric appliances. Specifically, it is an air source heat pump water heater, especially an ultra-low temperature air source heat pump water heater. Background technique [0002] With the development of social economy, the total demand for energy continues to increase, and the contradiction between the supply and demand of electricity, oil, coal and other energy sources has become more and more prominent. Energy issues have become an important factor restricting my country's economic and social development. In order to ensure energy conservation requirements, hot water The equipment is an energy-consuming product (except for solar water heaters). Due to the relative lack of water resources in my country, especially groundwater resources, this situation is even more serious in traditional hot water supply areas such as Sanbei; secondly, heat pump water heaters are used all year round...
