Problems solved by technology

That is, when the amount of sunlight is small, if the heat medium is directly supplied from the solar thermal collector to the absorption chiller, the heat medium with a low temperature will be supplied to the absorption chiller, and efficient operation cannot be performed.

Embodiment Construction

[0051] Next, preferred embodiments of the present invention will be described based on the drawings. figure 1 It is a schematic configuration diagram of an absorption refrigeration system according to an embodiment of the present invention. Such as figure 1 As shown, the absorption refrigeration system 1 according to this embodiment heats the dilute solution of the heat absorption refrigerator 21 using solar energy, and includes a first system 10 , a second system 20 , and a third system 30 .

[0052] The first system 10 heats the heat medium by using solar heat, and includes a solar heat collector (heat collector) 11 , a heat storage tank 12 , a heat collection flow path 13 , and a heat collection pump 14 . In addition, in this embodiment, the first system 10 uses solar heat to heat the heat medium, but it is not limited to this, and the heat medium can also be heated by exhaust heat, and renewable energy such as geothermal energy and biomass can also be used (which can be u...

Abstract

An absorption-type refrigeration system (1) equipped with: a solar heat collector (11); an absorption-type refrigerator (21); a circulation circuit (31); branch flow paths (34a, 34b); a changeover valve (33a); a cold storage tanks (32); and a system controller (44) that transmits a cold storage operation signal to the absorption-type refrigerator (21) when a prescribed condition is satisfied, and stops transmitting the cold storage operation signal to the absorption-type refrigerator (21) when the prescribed condition is not satisfied. When the cold storage operation signal has been transmitted the system controller (44) controls the changeover valve (33a) and causes coolant from the absorption-type refrigerator (21) to flow into the branch flow paths (34a, 34b), and the absorption-type refrigerator (21) sets a lower target temperature for the coolant in a first circulation path (31a) when a cold storage operation signal is received from the system controller (44) than when a cold storage operation signal is not being received from the system controller (44).

Description

technical field [0001] This invention relates to absorption refrigeration systems. Background technique [0002] Conventionally, a solar thermal utilization system has been proposed including a solar thermal collector that heats a thermal medium by receiving sunlight, and a thermal storage tank that introduces the thermal medium heated by the solar thermal collector to store heat. In addition, in such a solar heat utilization system, an absorption refrigeration system has been proposed in which pipes are connected between the heat storage tank and the absorption refrigerator, and a heat medium is circulated between them, thereby contributing to the regeneration of the absorption refrigerator. It is used to heat dilute solution in the container (refer to Patent Document 1). [0003] According to this absorption refrigeration system, the dilute solution can be heated using renewable energy such as solar heat, and the fuel cost required for heating the dilute solution can be r...
