Embodiment Construction
[0034] In order to describe the technical content, structural features, achieved goals and effects of the invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0035] Such as figure 1 As shown, the full frequency conversion heat pump unit with transcritical carbon dioxide gas supplement system includes frequency conversion compressor 1, air cooler 2, regenerator 3, economizer 4, first throttle valve 5, second throttle valve 6, evaporation device 7 and the controller.
[0036] The variable frequency compressor 1 can be a DC variable frequency compressor or an AC variable frequency compressor, and a first temperature sensor A is arranged on one side of the gas outlet. The inside of the air cooler 2 has a first heat exchange pipeline 21 and a water exchange circuit 22 that exchange heat with each other. The frequency conversion water pump 10 is connected to the water exchange channel 22. The frequency conv...

The invention discloses a transcritical carbon dioxide full frequency conversion heat pump unit with an air supply system. The transcritical carbon dioxide full frequency conversion heat pump unit comprises a frequency conversion compressor, an air cooler, a heat regenerator, an economizer, a first throttle valve, a second throttle valve, an evaporator, a gas-liquid separator and a controller; the frequency conversion compressor, a first heat exchange pipeline of the air cooler, a second heat exchange pipeline of the heat regenerator, a fourth heat exchange pipeline of the economizer, the first throttle valve, the second throttle valve, the evaporator, a third heat exchange pipeline of the heat regenerator and the gas-liquid separator sequentially communicate to form a main loop for circulation of a carbon dioxide refrigerant; the frequency conversion compressor, the first heat exchange pipeline of the air cooler, the second heat exchange pipeline of the heat regenerator, the fourth heat exchange pipeline of the economizer, the first throttle valve and a fifth heat exchange pipeline of the economizer sequentially communicate to form an air supply loop for the circulation of the carbon dioxide refrigerant, and a plurality of temperature sensors are arranged on the main loop and the air supply loop. Therefore, the controller controls all the components to work, and the temperature of one side of a water outlet of a heat exchange water path reaches the set temperature.
Description
technical field [0001] The invention relates to the technical field of carbon dioxide heat pumps, in particular to a full-frequency conversion heat pump unit with a transcritical carbon dioxide gas supply system. Background technique [0002] The heat pump using natural working substance carbon dioxide as refrigerant is called carbon dioxide heat pump. The carbon dioxide heat pump uses the thermophysical properties of carbon dioxide to exchange heat with water to form a huge temperature slip, which is very conducive to water side absorption. The overall system is used for hot water production performance very talented. However, in the actual use process, due to the influence of changes in ambient temperature and inlet water temperature, and the different requirements of the user side for outlet water temperature, ordinary transcritical carbon dioxide systems cannot meet the requirements of different ambient temperatures and different inlet water temperatures. How to provide...
