Can COP of refrigerator be less than 1?

Generally, T1 and T2 difference is less than T2 so efficiency is always greater than 1. Hence the correct answer is option (A). Thus, we can say that the COP of the refrigerator and air-conditioner can be less than one or greater than one. Click to see full answer Can the COP of a heat…

What is Rankine cycle TS diagram?

The Rankine Cycle, which is illustrated in Fig. 2 [5], is the basis for how thermal power plants operate. The cycle includes four processes: (1-2) isentropic compression on the pump; (2-3) constant pressure heat addition in a boiler; (3-4) isentropic expansion in a turbine; and (4-1) constant pressure heat rejection in a condenser. Click to…

What is the difference between CFM and CFM?

SCFM and CFM are both essential values that indicate the airflow rate in a compressor. SCFM measures this value based on 'ideal' temperature and pressure conditions, while CFM measures the 'actual' air flow rate. CFM is the recognized value for measuring the airflow rate in the United States. Click to see full answer What is…

Is a Rankine cycle a closed system?

Figure 1. In a closed-cycle system known as a Rankine cycle, a working fluid passes through a minimum of an evaporator, turbine, condenser, and pump in order to convert heat into work. If the temperature of the working fluid and heat source permits it, the evaporator may also incorporate or be followed by a superheater.…

What is ideal refrigeration cycle?

The vapor-compression refrigeration cycle is the ideal model for refrigeration systems. Unlike the reversed Carnot cycle, the refrigerant is vaporized completely before it is compressed and the turbine is replaced with a throttling device.
