Abstract

Sposób kondensacji i dochładzania cieczy czynnika chłodniczego urządzeń chłodniczych ze skraplaczami chłodzonymi powietrzem, w którym do skraplania i dochładzania czynnika chłodniczego wykorzystuje się lamelowy, chłodzony powietrzem skraplacz (1.2), który dodatkowo nawilża się i który chłodzi się powietrzem chłodzonym wodą, charakteryzuje się tym, że do nawilżania skraplacza (1.2) i chłodzenia powietrza chłodzącego skraplacz (1.2) używa się wodę deszczową zgromadzoną w zbiorniku wody deszczowej (3), przy czym dodatkowo czynnik chłodniczy chłodzi się także zasilanym wodą deszczową dochładzaczem (1.8), który w postaci wymiennika ciepła woda-czynnik chłodniczy umieszcza się na przewodzie cieczowym czynnika chłodniczego (1.7). Układ do kondensacji i dochładzania cieczy czynnika chłodniczego urządzeń chłodniczych ze skraplaczami chłodzonymi powietrzem, jak chłodzonych powietrzem sprężarkowych agregatów skraplających, chillerów i tym podobnych, utworzony z agregatu chłodniczego (1) zbudowanego ze skraplacza (1.2) w postaci lamelowego wymiennika ciepła powietrze-czynnik chłodniczy oraz parowacza (1.1), które wzajemnie ze sobą połączone są wyposażonym w sprężarkę (1.4) przewodem gazowym czynnika chłodniczego (1.5) oraz wyposażonym w zawór rozprężny (1.6) przewodem cieczowym czynnika chłodniczego (1.7), a poza powyższym także z przetłaczającego przez skraplacz (1.2) powietrze wentylatora (1.3) oraz zespołu do nawilżania skraplacza i chłodzenia powietrza chłodzącego (1.15) skraplacz (1.2), charakteryzuje się tym, że w przewód cieczowy czynnika chłodniczego (1.7) wbudowany jest dochładzacz (1.8) w postaci wymiennika ciepła woda-czynnik chłodniczy, przy czym skraplacz (1.2) oraz dochładzacz (1.8) połączone są przewodem (4) ze zbiornikiem wody deszczowej (3).A method of condensing and subcooling a liquid refrigerant of refrigeration devices with air-cooled condensers, wherein a lamellar, air-cooled condenser (1.2) is used for condensing and subcooling the refrigerant, which is additionally humidified and cooled with water-cooled air, is characterized in that rainwater collected in a rainwater tank (3) is used for humidifying the condenser (1.2) and cooling the air cooling the condenser (1.2), and wherein the refrigerant is additionally cooled by a rainwater-fed subcooler (1.8), which is placed on the liquid conduit of the refrigerant (1.7) in the form of a water-refrigerant heat exchanger. A system for condensing and subcooling the liquid refrigerant of refrigeration devices with air-cooled condensers, such as air-cooled compressor condensing units, chillers and the like, formed by a refrigeration unit (1) consisting of a condenser (1.2) in the form of a lamella air-to-refrigerant heat exchanger and an evaporator (1.1), which are interconnected by a gas refrigerant line (1.5) equipped with a compressor (1.4) and a liquid refrigerant line (1.7) equipped with an expansion valve (1.6), and in addition to the above also by a fan (1.3) for forcing air through the condenser (1.2) and a unit for humidifying the condenser and cooling the cooling air (1.15) the condenser (1.2), is characterized in that a subcooler (1.8) in the form of a finned air-to-refrigerant heat exchanger is built into the liquid refrigerant line (1.7) water-refrigerant heat exchanger, wherein the condenser (1.2) and the subcooler (1.8) are connected by a pipe (4) to the rainwater tank (3).
