WebTotal calculated refrigeration load (sum of Items 1 to 7) = 23411 kcal/h Total refrigeration requirement with allowances 23411 × 24 ÷ 18 = 31215 kcal/h If a pump is used to circulate refrigerant, the heat equivalent must be added to the capacity of the refrigeration condensing unit but not to the capacity of the room cooler. WebFeb 7, 2010 · In a vapour compression refrigeration plant, freon 12 enters the compressor at a pressure and temperature of 1.826 bar and −10°C respectively. It is compressed to a pressure and temperature of 7.449 bar and 45°C respectively. The refrigerant leaves the condenser at 25°C. Calculate: (a) the refrigeration effect; (b)

WebSince 1 kW = 3412 Btu/h - COP for 1 ton cooling can be calculated as. COP = (12000 Btu/h) / ((1 kW) (3412 Btu/h / kW) = 3.52. A small cooling unit operating at 1 ton per kW (1000 watts) is equivalent to a COP of 3.52 or an EER power of 12. The relationship between EER power and COP can be expressed as. EER power = 12 / 3.52 COP = 3.41 COP WebSep 9, 2024 · By the first law of thermodynamics, the denominator of the expression is Q2 − Q1, and for a reversible Carnot cycle, the entropy in equals the entropy out, so that Q2 / Q1 = T2 / T1. Therefore the coefficient of performance for a Carnot refrigeration cycle can be calculated from (11.8.5) T 1 T 2 − T 1. A cooling tower ton is defined as: 1 cooling tower ton = 1 TONSevap = 1 TONScond x 1.25 = 15000 Btu/h = 3782 k Calories/h = 15826 kJ/h = 4.396 kW The equivalent ton on the cooling tower side actually rejects about 15000 Btu/h due to the heat-equivalent of the energy needed to drive the chiller's … See more The process of cooling is called refrigeration.
