CHAPTER 10 EXAMPLES SOLUTION 1) An ideal vapor-compression refrigerant cycle operates at steady state with Refrigerant a as the working fluid. Saturated vapor enters the compressor at C, and saturated liquid leaves the condenser at C. The mass flow rate of refrigerant is 5 kg/min. Determine (a) The compressor power, in kWFile Size: KB. Mechanical refrigeration processes, of which the vapor compression cycle is an example, belong to the general class of reversed heat engine cycles, Figure figure represents, schematically, the extraction of heat at rate from a cold body at temperature T process requires the expenditure of work W and the sum is discharged at a higher temperature T H.

In the experiments, uncertainties of the water flow rate, the water temperature, and the power are ±%, ± °C, and ±%, respectively. Under the rating condition of full load in E mode (ARI, ), the cooling capacity and COP of chiller A is kW and , by: This work applies the second-law analysis of thermodynamics to quantify the exergy destruction of the components of screw liquid chiller, and to identify the potential for each component to contribute to improve the overall energy efficiency of the system. Three screw liquid chiller units were built to demonstrate the feasibility of the model presented by:

The real vapor compression cycle is illustrated in Fig With the help of a T-s diagram for the operating pressure limits p 1 & p 2. The definite compression follows 1 - 2' rather causing considerable difference because of the irreversibility's belonged with the compression procedure 1 - 2. is with vapor-compression cycles, because it is fairly easy to construct a cooling device employing this method and the cost is low. In fact, conventional refrigerators use this method of cooling to keep your leftovers and drinks chilled! Air conditioners also employ a vapor-compression cycle to cool the ambient air temperature in a Size: 61KB.

An air conditioning system of kW cooling capacity was developed using double-pipe evaporator and condenser in the present experimental study. The system runs on a standard vapor compression refrigeration cycle and consists of four major components: an evaporator, a condenser, capillary tubes, and a by: is the Air-conditioning and Refrigeration Institute document entitled "Standard for Water Chilling Packages Using the Vapor Compression Cycle," (ARI ,).

ARI Find out what they are by looking at the Simple Practical Cycle. Maximum Efficiency of the Vapour Compression Cycle It takes a lot of heat to evaporate liquid. In other words a small amount of liquid circulating in a refrigerator can perform a large amount of cooling.

This is one reason why the vapour compression cycle is widely used. Vapor Compression Vapor compression refrigeration offers several important advantages.

These include low mass flow rate, high COP, low cold plate temperatures and the ability to transport heat away from its source. The following is a more detailed look at vapor compression refrigeration of high performance electronics.

Vapor Compression. The Vapor-Compression Refrigeration Cycle (Eq. ) Applying mass and energy rate balances The term is referred to as the refrigeration capacity, expressed in kW in the SI unit system or Btu/h in the English unit system.

A common alternate unit is the ton of refrigeration which equals Btu/min or about kJ/min. 1 4 in h h m Q = −. Simple Vapor Compression Cycle. Figure below shows the simple vapor compression cycle: Figure Simple Vapor Compression Cycle. Process The refrigerant as a mixture of liquid and vapour corresponding to state point 1 enters the compressor where isentropic compression takes place.

Refrigeration cycle is the basis of all refrigeration systems. So refrigeration cycle should be known to understand the refrigeration system. Some basic refrigeration cycles are discussed here through different diagrams.
