FIELD: minor power engineering; heating and cooling of rooms containing perishable goods. SUBSTANCE: placed in helium heater is tube heater filled with cold-and-heat transfer agent boiling within temperature interval between water boiling and freezing points, including benzene, methyl alcohol, carbon disulfide, etc. hydraulically transferring heat from sun to evaporator mounted in refrigerating chamber provided with cold air registers and then to condenser mounted in thermal chamber provided with warm air registers. Thus, range of solar plant is extended and it is simultaneously used for production of heat and cold. EFFECT: enhanced efficiency. |
