Based on the study of the performance for the solar steam jet refrigeration system

the experiment takes R134a as the refrigerant and uses the control variable method to study the influence of the evaporation temperature and generator temperature on the ejection coefficient

the cooling capacity and the COP of the refrigeration system. The results show that:when the condensing temperature and generator temperature are constant

the injection coefficient

refrigerating capacity and COP increase with the increase of evaporation temperature. When the condensing temperature is 35℃ and the evaporation temperature is 6℃

the generator temperature is below 66℃

and the injection coefficient

refrigerating capacity and COP are 0. When the generator temperature is more than 66℃

the injection coefficient

refrigerating capacity and COP increase first and then decrease with the increase of temperature. When the generator temperature is 84℃

the maximum values are 0.223

2.02 kW and 0.204 respectively.
