Embodiment 1

[0023] Embodiment 1: as figure 1 As shown, an energy storage interconnected heat pump system suitable for heating in cold areas includes a main compressor 11, a water-cooled first heat exchanger 12, a main expansion valve 13, a water-cooled second heat exchanger 14, and a secondary compressor 21 , a water-cooled third heat exchanger 22, a secondary expansion valve 23, an air-cooled fourth heat exchanger 24, and an energy-storage heat exchanger 3 with a heat storage medium inside, the first, second, third, and fourth One side of the heat exchanger is the input part 31, and the other side is the output part 32, so that heat exchange can be realized between the respective input part and output part, and the heat is transferred from the higher temperature input part or output part side To the cooler output or input side, in other words, cooling is transferred from the cooler input or output side to the higher temperature output or input side. Similarly, one side of the energy sto...

Embodiment 2

[0032] Embodiment 2: Except for the fourth heat exchanger, the basic structure of this embodiment is the same as that of Embodiment 1, specifically, as Figure 4 As shown, the fourth heat exchanger 24 includes a cover body 241, a left heat exchange fin 242 and a right heat exchange fin 243 vertically arranged in the cover body, and grille-shaped air inlets are respectively provided on the left and right side walls of the cover body. 244. The left and right heat exchanging fins intersect to form a V shape. The V-shaped openings of the left and right heat exchanging fins face the front side wall of the cover body, and a cooling fan 245 facing the front side of the cover body is arranged on the front side wall of the cover body. When the fourth heat exchanger is working, a negative pressure is formed in the cover through the heat dissipation fan. At this time, the air outside the cover enters the cover through the air inlet holes on the left and right sides of the cover, and the a...

Embodiment 3

[0033] Embodiment 3: Except for the fourth heat exchanger, the basic structure of this embodiment is the same as that of Embodiment 1, specifically, as Figure 5 As shown, the fourth heat exchanger 24 includes a cover body 241, a left heat exchange fin 242 and a right heat exchange fin 243 vertically arranged in the cover body, and grille-shaped air inlets are respectively provided on the left and right side walls of the cover body. 244. The left and right heat exchanging fins intersect to form a V shape. The V-shaped openings of the left and right heat exchanging fins face the front side wall of the cover body, and a cooling fan 245 facing the front side of the cover body is arranged on the front side wall of the cover body. When the fourth heat exchanger is working, a negative pressure is formed in the cover through the heat dissipation fan. At this time, the air outside the cover enters the cover through the air inlet holes on the left and right sides of the cover, and the a...

Abstract

The invention discloses an energy storage interconnected heat pump system suitable for heating in cold areas, comprising a main heat pump system composed of a main compressor, first and second heat exchangers, a main expansion valve, a secondary compressor, a third and a fourth An auxiliary heat pump system consisting of a heat exchanger and a secondary expansion valve, the second heat exchanger is connected to an energy storage heat exchanger through a pipeline to form a first external circuit, and the third heat exchanger communicates with an energy storage heat exchanger through a pipeline connected to form a second external loop. The invention generates low-temperature heat energy through the auxiliary heat pump system and stores it in the energy storage heat exchanger, so that the main heat pump system can work in a reasonable temperature range, which is beneficial to reduce the compression ratio of the compressor, thereby improving the performance of the compressor and making the The system can be used normally in cold regions, which is conducive to improving the environmental pollution caused by burning coal for heating in winter.

Description

technical field [0001] The invention relates to a heat exchange system, in particular to a high-efficiency heat pump type heating system suitable for cold regions. Background technique [0002] At present, central heating in winter mainly uses hot water produced by burning coal, oil, gas and other fuels to heat residential buildings, etc., but there is a relatively serious environmental pollution, especially a serious impact on air quality. For this reason, people began to try to use heat pump heating technology to meet the heating demand in winter. The existing heat pump heating systems mainly include air source heat pump systems and water source heat pump systems. Heat pump systems usually include compressors, heat exchangers for heating Condenser (condenser), cooling heat exchanger (evaporator), the basic working principle of the heat pump heating system: First, the low-temperature (same as the ambient temperature) low-pressure gaseous refrigerant is compressed by the com...
