Energy storage water cooler working principle diagram

How does a cooler work?

The working principle of a cooler, or for that matter, a refrigerator or air-conditioner, is quite simple: introduce the object whose temperature you wish to decrease to an even colder object, so that when the heat from the hot object is transferred to the colder object, the former is rendered cold.

What are the components of a water cooler?

Water cooler has a metal sheet cabinet. It consists of a hermetically sealed compressor, condenser, capillary tube, accumulator, refrigerant coil, water cooling coil, thermostat, relay, overload protection etc. Thermostat is provided to control the temperature of water. Separate inlet and outlet connections of water are provided to storage tank.

What is a water cooler used for?

Function: Water coolers are used to give cold water having temperature, around 8°C to 16°C for drinking purpose. The three types of water coolers are Bottle type. Figure 1: Storage type water cooler. In storage type, tap water (water to be cooled) is stored in large size storage tank, surrounded by cooling coil (see Figure 1).

How to calculate cooling load for a water cooler?

For determination of cooling load for the water cooler (Q) the following relation may be used Q = m w x C p (T i – T 0) where m w is rate of water consumption in kg, C p is the specific heat of water in kJ/kg/K, T i is the temperature of inlet water and T 0 is the temperature of outlet water.

What are the three types of water coolers?

The three types of water coolers are Bottle type. Figure 1: Storage type water cooler. In storage type, tap water (water to be cooled) is stored in large size storage tank, surrounded by cooling coil (see Figure 1). It takes more time in the beginning to lower the temperature of water. It is generally used in schools, offices, hospitals etc.

What is a storage type water cooler?

Cycle used: Vapour compression cycle. Refrigerant: R-134a. The storage type water cooler has an evaporator coil soldered on the outside surface of the wall. The tank is made of stainless steel or GI sheet. The water level in the water tank is maintained and controlled by a float valve. Construction: Water cooler has a metal sheet cabinet.
