Problems solved by technology
However, when the outdoor temperature is low in winter, the condenser, especially the heat-absorbing fins, is prone to frost, and the gap between the heat-absorbing fins is blocked by frost. After the unit works for a long time, the entire condenser will be frozen into ice. The increase of energy consumption causes the heat absorption efficiency to drop sharply, and finally the heat absorption efficiency is zero
The existing defrosting technology generally uses the heat of the medium to defrost through the four-way reversing valve, and some heating rods are installed next to the condenser for electric heating. These two defrosting technologies still consume relatively large energy consumption and low efficiency. If the temperature is below 5 degrees, the defrost cannot be completely defrosted, which will cause the heating device to fail to work normally.

The invention relates to a defrosting condenser for an outdoor unit of a heating device and a defrosting control method of the defrosting condenser. By the defrosting condenser and the defrosting control method, the heat device can fully meet the requirement on heating, energy consumption can be reduced, and energy resources are saved. According to the technical scheme, the defrosting condenser comprises a copper tube and heat absorption fins, and is characterized in that heating tapes are mounted on an exposed part of the copper tube and the heat absorption fins; the heating tapes and a compressor are all electrically connected with a controller; the controller is further electrically connected with the condenser or a temperature sensor and a humidity sensor in a water storage tank of a heat pump unit; and the copper tube is communicated with the compressor, a heat evaporator in the water storage tank of the heat pump unit, or an indoor unit. The defrosting control method specifically includes that when the environment temperature, the condenser temperature and the air humidity are lower than a certain numerical point, the heating tapes, the compressor and a fan are controlled to work, and frost resisting and defrosting are performed for the condenser.
Description
technical field [0001] The invention relates to a heating device, in particular to a defrosting condenser of an air source heat pump unit or a heating air conditioner, and a defrosting control method for the condenser. Background technique [0002] Heating devices such as air energy heat pump units (i.e. air energy water heaters) and heating air conditioners are heating and heating equipment widely used in homes, hotels, restaurants, etc. Both units have an outdoor unit, the main components of which are the condenser and compressor. The condenser is mainly composed of heat-absorbing fins and copper tubes. The copper tubes are filled with heat transfer medium. The compressor connected to the copper tubes does work to compress the medium into high-temperature and high-pressure gas, which makes the heat in the thermal insulation storage tank in the connected heat pump unit The evaporator or the air heating of the indoor unit of the heating air conditioner heats up the temperat...
