Description

Dual purpose heat pump air conditioning system

technical field

The utility model relates to a heat pump air-conditioning system capable of cooling and producing domestic hot water, which belongs to the field of heat pump air-conditioning equipment.

Background technique

The improvement of people's living standards, on the one hand, makes the penetration rate of household air conditioners higher and higher. Due to performance limitations, household air conditioners are mainly used for indoor cooling in summer, and the heating time is very short in winter, and they are idle most of the year. On the other hand, the consumption of domestic domestic hot water is also increasing year by year. And existing various water heaters mainly contain electric water heater, gas water heater and solar water heater. Although electric water heaters and gas water heaters are easy to use, they all have disadvantages such as potential safety hazards and insufficient energy saving; although solar water heaters can overcome the above shortcomings, due to the influence of the weather, it is difficult to guarantee daily domestic water requirements in the case of insufficient solar energy, resulting in solar energy. Water heaters cannot independently guarantee a continuous hot water supply throughout the year, and generally require an auxiliary heat source, which results in a decline in their economy. Therefore, relatively energy-saving heat pump water heaters have developed to a certain extent in recent years, but because they require a complete heat pump system and have high costs, it is difficult to popularize them at present. Therefore, researchers have proposed various air-conditioning and water-heating integrated machines (or multi-functional heat pump systems), and proposed systems in various ways, in order to allow the air-conditioning system to have multiple functions such as cooling, heating, and hot water production. Theoretically, the all-in-one air conditioner and water heater can realize the functions of air conditioner and heat pump water heater, and the cost increase is less, and the utilization efficiency of the equipment can be greatly improved throughout the year. However, at present, most researchers have created too many system components in order to achieve multiple functions, which makes the system reliability and stability of the air conditioner and water heater integrated machine not high, thus affecting its practicability and making it difficult to popularize and apply. Therefore, it is necessary to improve the integrated air conditioner and water heater system to improve the reliability and practicability of the system, so as to be popularized and applied.

Referring to Figure 1, the dual-purpose heat pump air-conditioning system includes a compressor 1 and a four-way reversing valve 2, and the compressor 1 is connected to the four-way reversing valve 2. It is characterized in that one interface of the four-way reversing valve 2 is connected to the outdoor The air-cooled condenser 3 and the other interface of the four-way reversing valve 2 are connected to the indoor evaporative air cooler 4 and the water-cooled condenser 5 through pipelines, the indoor evaporative air cooler 4 is connected in parallel with the water-cooled condenser 5, and the indoor evaporative air cooler 4 The other side of the water-cooled condenser 5 is connected with a check valve 8 and then connected with the outdoor air-cooled condenser 3, and the other side of the water-cooled condenser 5 is connected with a check valve 9 and then connected with the outdoor air-cooled condenser 3.

The water-cooled condenser 4 is provided with a circulating water pipe, and the circulating water absorbs the heat released by the water-cooled condenser 4 when passing through the water-cooled condenser 4, thereby achieving the purpose of heating and preparing hot water.

A throttling device 6 is arranged on the branch of the indoor evaporative air cooler 4, and adjusting the throttling device 6 can control the power of the whole machine.

The branch of the water-cooled condenser 5 is provided with a throttling device 9, and adjusting the throttling device 9 can control the power size of the whole machine operation.

When realizing refrigeration and air-conditioning functions (refrigeration, dehumidification), the four-way reversing valve 2 is not powered, and the high-temperature and high-pressure working medium discharged from the compressor 1 passes through the four-way reversing valve 2 and first passes through the outdoor air-cooled condenser 3 to release heat to the outdoor environment , then through the throttling device 6 and the one-way valve 8, the throttling device can be adjusted to control the power of the entire machine, and then through the indoor evaporative air cooler 4, the indoor evaporative air cooler 4 works to absorb heat from the room to achieve cooling, and finally After passing through the four-way reversing valve 2, it returns to the compressor. When this function is running, the one-way valve 9 prevents the working fluid from passing through the branch where the water-cooled condenser 5 and the throttling device 7 are located.

When realizing the hot water production function of the heat pump water heater, the four-way reversing valve 2 is energized, and the high-temperature and high-pressure working fluid discharged by the compressor 1 passes through the four-way reversing valve 2 and then first releases heat through the water-cooled condenser 5, and at the same time, due to the water-cooled condensed gas 5 There is a circulating water pipeline, so the water passing through the circulating water pipeline can achieve the effect of heating by absorbing the heat released by the water-cooled condenser 5. The high-temperature and high-pressure working medium then passes through the throttling device 7 and the one-way valve 9 to adjust the throttling device 7 It can control the power of the whole machine, and then pass through the outdoor air-cooled condenser 3. At this time, the function of the air-cooled condenser 3 is an evaporator, which absorbs heat from the environment. Finally, the high-temperature and high-pressure working medium passes through the four-way reversing valve 2 Back to compressor 1. When this function is running, the one-way valve 8 prevents the working fluid from passing through the branch where the indoor evaporative air cooler 4 and the throttling device 6 are located.
