Device for high-efficiency energy heating under low temperature condition, and control method thereof

Abstract

The invention relates to the technical field of air source heat pump high-efficiency heating under multiple working conditions particularly a low-temperature environment, in particular to a device forhigh-efficiency energy heating under a low temperature condition, and a control method thereof. A low-temperature air source module is connected between an energy storage water tank and a high-temperature water source screw rod unit; the high-temperature water source screw rod unit outputs high-temperature water to an end user side; electric auxiliary heating is arranged between the high-temperature water source screw rod unit and the end user side; an end water supplement pump is arranged on the water outlet side from the energy storage water tank to an end pipe network; a low-temperature condenser of the low-temperature air source module and a high-temperature system evaporator of the high-temperature water source screw rod unit are cyclically coupled through a waterway; and the low-temperature water source module prepares low-temperature hot water used as a low-temperature heat source of the high-temperature water source screw rod unit. According to the device for high-efficiency energy heating under the low temperature condition, and the control method thereof provided by the invention, the low-temperature adaptability of the air source heat pump can be improved, and a low-temperature heating performance is improved.

Description

technical field [0001] The invention relates to the technical field of high-efficiency heating by an air source heat pump under multiple working conditions, especially in a low-temperature environment, and in particular to a high-efficiency energy heating device and a control method thereof under low-temperature conditions. Background technique [0002] The energy problem is a common concern in the world today, and it will also be a long-term problem in the future. Improving energy utilization efficiency has become the basic starting point of my country's energy development strategy. The research and practice in the energy field in the past 30 years has shown that building energy conservation is the most potential and most direct and effective way of energy conservation, and it is one of the most effective measures to alleviate the energy shortage and solve the contradiction between social and economic development and energy supply shortage. . Heating (air conditioning) ene...

Problems solved by technology

If this problem is not solved, the application of air source heat pumps in my country will be the same as in the 1960s in the United States. Due to the reliability of heat pumps, the development of heat pumps has stagnated, thus destroying the situation of ecological heating of air source heat pumps in my country and seriously affecting Building Energy Efficiency Work
