Problems solved by technology

[0003] However, due to the influence of refrigerant characteristics, technical level, manufacturing cost, etc., the outlet water temperature of the air source heat pump cannot be too high, and the highest is often only about 60°C, which is difficult to meet the market demand for high water temperature.
[0004] At present, the refrigerants of conventional air energy heat pumps include R22, R32, R410a, R134a, and R744 (CO2) refrigerants; among them, affected by the characteristics of refrigerants, R22, R32, and R410a refrigerants can adapt to low ambient temperature (-20°C), but heating The highest water temperature is about 60°C; R134a refrigerant can make hot water up to 85°C, but it is not suitable for low ambient temperature (-20°C); R744 (CO2) refrigerant can make hot water up to about 90°C, and can also be adapted to Low ambient temperature (-20°C), but due to the technical requirements and high manufacturing cost of the CO2 system, it has not yet been widely used commercially

Abstract

The invention provides a heating system and a control method for the heating system, wherein the heating system includes an air source heat pump, a water storage tank, a water source heat pump and a heating terminal connected in sequence; the air source heat pump and the water storage The tank forms the first circulation loop through the air source heat pump circulation pump; the water storage tank and the water source heat pump form the second circulation loop through the evaporation side circulation pump of the water source heat pump; the water source heat pump and the heat supply terminal form the third circulation loop through the heat supply terminal circulation pump . The heating system of the present invention effectively combines the air source heat pump and the water source heat pump to realize the heat output of high water temperature at the heating end under the condition of low environment. Meet the demand for high water temperature in the market, while making 2 System technology, low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heating system and a control method for the heating system. Background technique [0002] Air source heat pump, also known as air energy water heater, also known as air source heat pump water heater; by absorbing the low-temperature heat in the air, it is vaporized by fluorine medium, then compressed by a compressor, pressurized and heated, and then converted into water by a heat exchanger Heating, the high-temperature heat energy after compression is used to heat the water temperature. Air source heat pumps have the characteristics of high efficiency, energy saving, and high energy efficiency. In northern China, with the introduction of "clean heating" related policies, the use of air source heat pumps has increased. [0003] However, due to the influence of refrigerant characteristics, technical level, manufacturing cost, etc., the outlet water temperature of air so...
