Problems solved by technology

[0003] 1. When the water temperature of the water storage tank is higher than 43°C, the refrigerant system that performs heat absorption and heat release cycles is difficult to release heat due to the high external ambient temperature, which leads to high pressure in the refrigerant cycle system and makes the refrigerant It is difficult to effectively carry out the heat absorption and heat release cycle, thereby reducing the heating capacity of the refrigerant system;
[0004] 2. When the water storage tank is supplemented with tap water, due to the large temperature difference between the tap water and the water storage tank, it is easy to cause uneven water temperature and large temperature fluctuations in the water storage tank;
[0005] 3. When the sensor of the water storage tank has a temperature deviation, the exhaust temperature is often higher than the normal value, and the exhaust temperature of the compressor is too high for a long time, which will cause damage to the compressor and the four-way valve

Embodiment Construction

[0026] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Such as Figure 1-Figure 2 The shown heat pump system 1 includes a compressor 2 , a four-way valve 42 , a first condenser 31 , a second condenser 32 , a throttling device 5 and an evaporator 6 . The refrigerant circulates between the compressor 2, the four-way valve 42, the first condenser 31, the second condenser 32, the throttling device 5, and the evaporator 6, and the above-mentioned components are connected by pipelines, preferably Copper tubes are used, and the connection relationship between the above-mentioned components will be introduced in detail below.

[0028] The compressor 2 has a high-pressure discharge port 22 and a low-pressure suction port 21 , and the refrigerant enters the compressor 2 from the low-pressure suction port 21 and is discharged from the high-pressure discharge port 22 after being compressed...

Abstract

The invention discloses an efficient heat pump system, which comprises a compressor, a four-way valve, a first condenser, a second condenser, a throttling device and an evaporator, wherein the first condenser is connected in series between the compressor and the four-way valve. The heat pump system can be switched between a low-temperature heating mode and a high-temperature heating mode. The efficient heat pump system has the advantages that the heating efficiency is high, the water temperature fluctuation range is small, the compressor and the four-way valve are effectively protected, and the like.

Description

technical field [0001] The invention relates to a heat pump system. Background technique [0002] The heat pump system in the prior art mainly has the following defects: [0003] 1. When the water temperature of the water storage tank is higher than 43°C, the refrigerant system that performs heat absorption and heat release cycles is difficult to release heat due to the high external ambient temperature, which leads to high pressure in the refrigerant cycle system and makes the refrigerant It is difficult to effectively carry out the heat absorption and heat release cycle, thereby reducing the heating capacity of the refrigerant system; [0004] 2. When the water storage tank is supplemented with tap water, due to the large temperature difference between the tap water and the water storage tank, it is easy to cause uneven water temperature and large temperature fluctuations in the water storage tank; [0005] 3. When the sensor of the water storage tank has a temperature d...
