Impact-resistant liquid storage device, cross-critical carbon dioxide heat pump and fluorine-chlorine gas system refrigeration device

Abstract

The invention discloses an impact-resistant liquid storage device, a cross-critical carbon dioxide heat pump and a fluorine-chlorine gas system refrigeration device. The liquid storage device comprises a liquid storage tank body used for storing refrigeration media; a feeding pipe connected to a throttling valve is arranged at the top end of the liquid storage tank body, an anti-rolling spray headis arranged at the lower end of a feeding pipe, the anti-rolling spray head comprises herringbone discharge pipes which are separated from the two sides and flow to the inner wall of the liquid storage tank body, and a gaseous refrigerant outlet is formed in the middles of the herringbone discharge pipes; and a liquid outlet pipe connected to an evaporator is arranged at the bottom end of the liquid storage tank body. According to the anti-impact liquid storage device, the refrigerant flowing out of the anti-rolling spray head flows to the inner wall of the liquid storage tank body and then flows downwards along the inner wall, and the liquid refrigerant stored at the bottom of the liquid storage tank body cannot be subjected to impact rolling, so that gas is prevented from being entrained in the liquid refrigerant entering the evaporator, and the heat exchange effect of the evaporator is improved.

Description

technical field [0001] The invention relates to a liquid storage device used in the temperature regulation industry, in particular to an anti-shock liquid storage device, a transcritical carbon dioxide heat pump, and a Freon system refrigeration device. Background technique [0002] The liquid receiver plays the role of buffer and liquid storage in the heat pump and air conditioning system. When the refrigerant charge in the system is too large, it can store a part of the refrigerant in it to prevent the occurrence of excessive refrigerant charge. If the system pressure is too high, the heating and cooling capacity will decrease. The liquid reservoir in the prior art only has the function of simple buffering and liquid storage, and cannot give full play to the functionality of the liquid reservoir, and cannot achieve the optimal heat exchange effect of the heat exchanger; in addition, the storage in the prior art The refrigerant flowing into the liquid receiver from the thr...

Problems solved by technology

The liquid reservoir in the prior art only has the function of simple buffering and liquid storage, and cannot give full play to the functionality of the liquid reservoir, and cannot achieve the optimal heat exchange effect of the heat exchanger; in addition, the storage in the prior art The refrigerant flowing into the liquid receiver from the throttle valve directly flows to the bottom of the liquid receiver, which will easily cause the liquid at the bottom of the liquid receiver to roll over, resulting in unstable suction of the compressor; if there is less liquid refrigerant stored at the bottom of the liquid receiver, it will also As a result, the liquid refrigerant entering the evaporator entrains part of the gas, reducing the heat transfer effect of the evaporator; if there is more liquid refrigerant at the bottom of the liquid receiver, the liquid tumbling will cause the compressor to entrain liquid when sucking air
