Groundwater source heats up pump system heat exchanger to match a gender to consider

(The sources of energy of Central Plains engineering college and environmental institute Zhengzhou 450007)
Summary: The influence of the performance of matched pair system that ⒘ says to kind of impossible filter is short of Meng Di to showed? of flute goblet pa to study heat exchanger area respectively in the light of summertime operating mode and winter operating mode. Experimental result analysis makes clear, increase condenser area to be able to improve unit performance already appropriately, can avoid to be when winter operating mode again condensing pressure is exorbitant, make sure aircrew stability moves reliably.
Keyword: Kind of impossible filter is short of? experiment to study; heat exchanger
On the base that has labor to system and equipment, built groundwater source to heat up stage of pump system experiment. Systematic work flow is shown 1 times like the graph, experimental system basically includes refrigeration system, water system and test system. Compressor of type of the HF4524 that compressor chooses company of law Guo Taikang to produce vortex (output power is 2HP) , refrigeration agent chooses R22(CHF2Cl) , condenser and evaporator use a Yu town new fast can solder of the MTB020 of nimble abundant card that limited company of board type heat exchanger produces drill rod board type heat exchanger.
Because use real well fountainhead cost tall and have cover an area of a space to ask, consider the adjustability of temperature of water of the well in the experiment at the same time, use bath of water of two constant temperature to come imitate operating mode of all of two water system. Considering pure will drop cooling water temperature with bath of constant temperature water or promote refrigerant water temperature, consequent need very the bath of constant temperature water of high-power, and also can create energy waste at the same time. To make full use of the quantity of heat in cooling water is mixed the cold quantity in refrigerant water, in the experiment, choose a Yu city new fast can board type heat exchanger regards solder of the MTB020 of nimble abundant card that limited company of board type heat exchanger produces drill rod as cold quantity of heat intermediate heat exchanger.
Fall in different operating mode between area of the moving character to study a system better and well discharge, heat exchanger optimize match a relation, considering the adjustability of area of the heat exchanger when the experiment, in the experiment, evaporator and condenser use the means of paralell connection of heat exchanger of many groups of board type. Evaporator and condenser use 3 groups to differ respectively the heat exchanger of a number is shunt-wound, the first group (A group) the biggest heat exchanger that needs to design the place below operating mode piece several, 30; the 2nd group (B group) heat exchanger piece number is 20; the 3rd group (C group) heat exchanger piece number is 10 (graph 1) .
