Embodiment Construction

[0057] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0058] Please also refer to Figure 4 and Figure 5 , the gas-liquid separation device provided by the present invention will now be described. The gas-liquid separation device 7 includes a three-way pipe 71 having the first nozzle 711 , the second nozzle 712 and the third nozzle 713 . The third nozzle 713 is provided with a section of liquid storage pipe 72 for storing liquid refrigerant. In a preferred embodiment of the present invention, the three-way pipe 71 is a T-shaped three-way pipe, and in other embodiments, it may also be a Y-shaped three-way pipe. Th...

Abstract

The invention provides a gas-liquid separator, an air source heat recovery system comprising the gas-liquid separator, a water chiller and a heat pump, wherein the gas-liquid separator can synchronously detect two liquid levels through arranging a low liquid level switch and a high liquid level switch, outputs two switching value signals, can very conveniently judges whether condensate is generated in part of heat recovery devices and whether a condensate cold medium is enough to be used by an economizer, discharges or does not discharge a liquid according to the situation that whether the liquid exists or not, and does not affect the operation of a main system. According to the invention, the water chiller and the heat pump completely solve the problem that as the condensate is formed on cold medium side of part of the heat recover devices of part of the conventional air source heat recovery unit, pressure drop of the pipeline is increased and further performance of the whole machine and oil return of the compressor are affected are solved. In addition, heat recovery capacity can be improved to a great extent, and system capacity and efficiency are also improved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning system manufacturing, and more specifically relates to a gas-liquid separation device, an air-source heat recovery system with a partial heat recovery function using the gas-liquid separation device, and an air-source heat recovery system using the gas-liquid separation device chillers and heat pump units. Background technique [0002] Air source chillers or heat pump units with partial heat recovery may face condensation problems when the unit is operating in cooling mode with partial heat recovery turned on. [0003] See figure 1 , figure 1 The ordinate is the logarithmic value of absolute pressure lgP, the abscissa is the specific enthalpy value h, 1'-2' is the compression process completed in the compressor; 2'-3' is the process completed in the condenser, divided into The third section, 2'-5', is the cooling process of high-temperature and high-pressure gaseous refrigerant from th...
