Split type air source heat pump system

Abstract

The invention belongs to the technical field of clean energy heating and cooling, and domestic hot water, and discloses a large split type air source heat pump system. The split type air source heat pump system comprises an air heat exchanger, a circulation pump unit, an evaporator, an anti-freezing solution water tank, a compressor, a condenser and a buffer water tank. The anti-freezing solutionwater tank is connected with the air heat exchanger, the compressor is connected with the anti-freezing solution water tank, the condenser is connected with the compressor, and the buffer water tank is connected with the condenser. The compressor is connected with the air heat exchanger through an anti-freezing solution feeding header pipe. The air heat exchanger is connected with the anti-freezing solution water tank through an anti-freezing solution return header pipe. The buffer water tank is connected with a cold and hot water return header pipe and a cold and hot water supply header pipe.According to the large split type air source heat pump system, the air heat exchanger and a main machine are arranged separately, heat exchange is carried out between the air heat exchanger and the heat pump main machine through the anti-freezing intermediate heat exchange medium (coolant), an independent circulation system is arranged for the intermediate heat exchange medium to carry out circulation, the heat pump main machine can achieve long distance independent closed installation, vibration is weak, the noise is low, frosting is not prone to happening, energy consumption is low, and theheating scale is large.

Description

technical field [0001] This patent belongs to the technical field of clean energy heating, cooling and domestic hot water, and particularly relates to a large-scale split air source heat pump system. Background technique [0002] The air source heat pump uses the reverse Carnot cycle principle to absorb a large amount of low-temperature heat energy in the air with very little electric energy, and convert it into high-temperature heat energy through compression by a compressor. It is an energy-saving and efficient heat pump technology. When the air source heat pump is in operation, the evaporator absorbs heat from the ambient heat in the air to evaporate the heat transfer medium. The pressure and temperature of the working medium vapor are increased after being compressed by the compressor. When the high-temperature vapor is condensed into a liquid through the condenser, it is released The heat of the air source heat pump is transferred to the water in the water storage tank ...

Problems solved by technology

Due to this feature, the distance between the evaporative condenser and the main engine should not be too far, and due to the limitation of the space structure, there are the following disadvantages: the unit is heavy, difficult to install, and occupies a large area; the unit has strong vibration; the unit has high noise; the single unit power is small; Severe frost; unreliable ultra-low temperature operation, high energy consumption; small heating scale, difficult to heat large areas, etc.
