How to calculate cooling capacity? What is the formula

Method 1: Power and Area Method:

qt=q1+q2

The meaning of the letters in the equation is: Qt total cooling capacity (kW), Q1 indoor equipment load (equipment power, Q2 ambient heat load (= machine room area).

Method 2: Area Method:

qt=s xp

The meaning of the letters in the formula: qt total cooling capacity (kw), S equipment room area ( ) cooling capacity estimation index (selected according to the estimation index of different purpose computer rooms).

1 hp refers to the cooling capacity of roughly 2000 kcal, converted into SI units should be multiplied so the refrigeration capacity of 1 hp should be 2324 (W), where w (watts) represents the cooling capacity, then the hp should be 2000 kcal, and so on. According to this situation, it can roughly determine the number of horsepower and cooling capacity of the air conditioner, under normal circumstances, 2200W 2600W can be called 1 horse, 3200W 3600W can be called horsepower. Cooling capacity = compressor power * COP value (energy efficiency ratio).

2000*40* w=

Calculation method: 1: volume (liters) number of cooling temperature du cooling time (min) 60 coefficient) = (w).

2: Volume (tons or cubic meters) Cooling number Cooling time (hour) Coefficient) = (kw).

2. Refrigeration capacity.

It refers to the sum of the heat removed from a confined space, room or area per unit time when the air conditioner is running for refrigeration. Air conditioners with large cooling capacity are suitable for rooms with a relatively large area and fast cooling speed.

3. The principle of choosing the cooling capacity is: the cooling capacity of the air conditioner should be slightly greater than the cooling load of the room and the heat load of the room.

Consideration should be given to the orientation of the room, the insulation of the walls and roof, and the number of people included in the indoor heat source.

**Calculation of cooling capacity of air conditioner.

The nominal refrigeration capacity is only calculated according to the flow rate of chilled water. It is not possible to calculate the actual cooling capacity based on the given parameters.

Room cooling capacity calculation.

The amount of cooling required for this cannot be accurately calculated, because the insulation of the office building is unknown, the ventilation is unknown, and the number of doors and windows is unknown. But one thing is for sure, an office of this size is nowhere near enough to use the air conditioning of three horses. It is recommended to add another large air conditioner or replace the original air conditioner with about 6 air conditioners.

In this kind of office, the ventilation of the office should be taken into account while installing air conditioning, and it is recommended to install and use a full heat exchanger, that is, a fresh air ventilator.

The formula for calculating the room area and the required air conditioning and cooling capacity and heating capacity.

Generally speaking, the size is selected according to the cooling capacity of the air conditioner, and the selection range is 180 240w m2; It depends on the orientation of the room, the insulation conditions, the number of people, the number of electrical appliances in the room, the size of the door and window area and other factors.

How to calculate cooling capacity? What is the formula

The basic formula: q = w * c * δ t i.e.: cooling capacity kacl h = weight of material * specific heat * temperature difference (here you need to pay attention to the example of uniform conversion units:

1 m water from 20 - 10 1 m = 1000 l l = 1000 kgq = 1000 * 10 860 kcal hours (converted to kilowatts) q = 42000 kcal headquarters = kilowatts If the volume of the material is not determined to be important, if it is liquid, it can be calculated according to the flow rate of the pump, the formula: q = l * δt * l is the flow rate, calculated in m, and then the temperature difference, which is the abbreviated formula value in the industry. As mentioned above, there are two formulas for calculating the cooling capacity that can be applied to the selection and calculation of most refrigerators, but various factors need to be considered in a variety of different use cases and when dealing with different materials for cooling.

Extended data cooling capacity is the total amount of heat removed from a confined space, room, or area per unit of time while a chiller, such as an air conditioner, is running. Encyclopedia - Cooling capacity.

The basic formula: q=w*c*δt

That is: refrigeration capacity kacl h = material weight * specific heat * temperature difference (here you need to pay attention to the unified conversion of units).

Example: 1m of water is reduced from 20 to 10

1m³=1000l=1000kg

q=1000L*Convert to kw).

q=42000kcal/h

q = if it is not sure that the volume of the material is important, if it is a liquid, it can be calculated according to the flow rate of the water pump, the formula: q = l * δt *

l is the flow rate, and the unit of calculation is m, and then the temperature difference, which is the abbreviated formula value in the industry.

As mentioned above, these two refrigeration capacity calculation formulas can be applied to most freezer selection calculations, but various factors need to be taken into account in various use cases and when dealing with different material cooling.

Cooling capacity refers to the total amount of heat removed from a confined space, room or area per unit time when a chiller such as an air conditioner is running.
