Embodiment Construction
[0012] figure 1 Among them, 1 is a compressor, 2 is a condenser, 3 is a gas-liquid separator of the present invention, 4 is a throttling device, and 5 is an evaporator.
[0013] figure 2 Among them, 4 is the middle partition, which divides the gas-liquid separator into upper and lower cylinders, 1 is the lower cylinder, 5 is the upper cylinder, 6 is the superheating pipe, 7 is the supercooling pipe, 3 is the steam rising pipe, 2 For baffles.
[0014] When the heat pump is in heating operation, in the upper cylinder, the high-temperature condensate from the condenser enters the superheated pipe 6 in the upper cylinder from the main pipe a1 through the branch pipe a11, where it exchanges heat with the low-temperature gaseous condensate from the lower cylinder, so that The gaseous condensing agent has a certain degree of overheating, and then enters the compressor through b2, which effectively avoids the situation where the liquid droplets directly enter the compressor and pre...

The invention discloses a multifunctional gas-liquid separator used for a heat pump system. The multifunctional gas-liquid separator is a columnar cylinder, and is equipped with a middle clapboard with a ascending pipe for dividing the gas-liquid separator into an upper cylinder and a lower cylinder, a overheat pipe for overheating gaseous condensing agent at low pressure side is arranged in the upper cylinder, can effectively avoids liquid drop from directly entering into a compressor and liquid impact phenomenon, and improves life of the compressor; a supercooling pipe for supercooling liquid condensing agent at high pressure side and reboiling liquid drop at the low pressure side is arranged at the lower cylinder, improves heat transferring performance of a evaporator, working environment of a expansion valve, and low-temperature performance of a heat pump, and effectively increases heating capacity. The separator has multiple functions and simple structure, and can be used for heat pump circulation, especially heat pump heat supply circulation.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to the field of heat pump heat supply cycle. Background technique [0002] In order to prevent liquid droplets from directly entering the compressor, a gas-liquid separator is usually installed before the suction port of the compressor to avoid liquid hammering of the compressor. [0003] However, in fact, even if a gas-liquid separator is installed, it is still unavoidable that liquid droplets enter the compressor, and sometimes it is even serious. The increase of unevaporated liquid condensate increases the possibility of liquid hammer being sucked into the compressor by increasing the liquid droplets. [0004] In order to reduce the amount of liquid condensate in the separator, some additional energy is input into the separator, such as solar energy, electric energy and thermal energy, in order to evaporate a part of the liquid droplets in the separator. However, even so, it can...
