Quick water heating device for heat pump

Abstract

The invention discloses a quick water heating device for a heat pump, which comprises a Carnot cycle system. The quick water heating device for the heat pump further comprises a water storage tank, and a water pipe arranged outside the water storage tank; the bottom of the water storage tank is provided with a water intake; the top of the water storage tank is provided with a circulating water outlet; the circulating water outlet is connected with a water inlet of the water pipe; a water outlet of the water pipe is connected with the water intake of the water storage tank via a circulating water pump and a check valve in sequence; a pipeline between the water outlet of the water pipe and the circulating water pump is provided with a water outlet for bath; and the water pipe is arranged side by side with a refrigerant pipe in the Carnot cycle system to form a heat exchanger. By means of the quick water heating device for the heat pump, disclosed by the invention, the water can be pre-heated and heated quickly, and the service life of the equipment can be prolonged.

Description

technical field [0001] The invention relates to a hot water device, in particular to a fast heat pump hot water device capable of rapidly heating water. Background technique [0002] Under normal circumstances, the water temperature suitable for human body bathing is about 45°C, and the structure of the existing heat pump water heater is that the water storage tank has a built-in condensing coil heat exchanger, and the refrigerant working medium absorbs the heat in the ambient air in the outdoor evaporation tube and becomes a gas , circulate through the compressor to the condensing coil to condense and release heat in the water storage tank, and gradually heat the water in the water storage tank, that is, directly heat the water inside the water storage tank for use. At present, the compressors used in household heat pump water heaters are all air-conditioning compressors. During the heating process of the water temperature, the air-conditioning compressors will be overloade...

AI Technical Summary

Problems solved by technology

At present, the compressors used in household heat pump water heaters are all air-conditioning compressors. During the process of water temperature rise, the air-conditioning compressors will be overloaded, which not only slows down the temperature rise, but also seriously affects the service life of the compressor.

Especially in winter, the temperature of cold water is generally about 9°C. To directly heat the cold water to 45°C in a short period of time, the kinetic energy required must be very large, and the power of the corresponding compressor must be large, and high-power compression The machine is not suitable for household power supply
