Overview Chiller

Chiller, is a kind of cooling water equipment that can provide constant temperature, constant flow, constant pressure, its working principle is that the refrigerant is compressed into a high temperature and high pressure gas through the compressor, and then through the condenser exothermic cooling and condensation, into a high-pressure liquid, and then throttled and expanded through the expansion valve, so that the refrigerant absorbs the heat and evaporates inside the evaporator, to achieve the purpose of refrigeration. Water chiller mainly through the circulation flow refrigerant to reduce the temperature. Water chillers are divided into two types: air-cooled chillers and water chillers.

Important parts

The chiller unit includes four main components: compressor, evaporator, condenser, and expansion valve, thus realizing the cooling and heating effect of the unit. Below, let’s disassemble the air-cooled chiller, Minnuo sells the whole machine, but also can sell the local refrigeration compressor, interested can contact us!

Working Principle

Compression: low temperature and low pressure refrigerant is sucked into the compressor, and through the compression process inside the compressor, the refrigerant is compressed into high temperature and high pressure gas.
Condensation: the high temperature and high pressure gas through the condenser exothermic condensation into high pressure liquid, at this time the heat will be released by the radiator heat dissipation into the air, so that the refrigerant cooling.
Expansion: After the expansion valve, the high pressure liquid flows into the low pressure area, the pressure decreases, while the flow rate is accelerated, the refrigerant expands and the temperature decreases.
Evaporation: After expansion, the refrigerant enters the evaporator, absorbs the heat in the environment, evaporates into a low-temperature, low-pressure refrigerant, forming a refrigeration cycle.
Chiller mainly through these four steps to achieve the cooling effect, the high temperature and high pressure gas condensation into a high pressure liquid, and then through the throttling expansion so that the refrigerant evaporates and cools down, so as to achieve the purpose of refrigeration.0

Frequently Asked Questions

What is the energy efficiency ratio of a chiller?

The energy efficiency ratio (COP) of chiller units varies according to models and configurations, generally between 3.0 and 6.0. You can refer to the product specifications or consult the supplier for specific values.

What is the cooling capacity range of the chiller units?

Our chiller units offer a wide range of cooling capacities, from tens of kilowatts to thousands of kilowatts, to meet the needs of different sizes.

What are the installation and maintenance requirements for chiller plants?

Installation of chiller units requires consideration of space, ventilation, power and water sources. Maintenance includes regular inspection, cleaning of filters, replacement of lubricating oil and refrigerant, etc.

How long is the service life of a chiller?

Under normal use and maintenance, the service life of a chiller plant is usually around 15 to 20 years.

What is the noise level of the chiller during operation?

The noise level of a chiller unit is usually between 70 and 85 dB, depending on the model and size of the unit.

Does the chiller support remote monitoring and control?

Yes, many chiller units are equipped with remote monitoring and control features that allow real-time monitoring and control via the internet.

Buyer Guide

Select the cooling capacity according to the need. The cooling capacity is the most important parameter of the chiller, and the selection should be based on the size of the area to be cooled and the heat load. If not selected properly, the whole system may fail due to insufficient cooling.
Consider the ease of maintenance, cleaning and upkeep of the unit. Maintenance and cleaning of the unit is a very important maintenance task during the use of the chiller, as dust and dirt will affect the performance of the cooling system.
Choose energy-saving chillers. Energy-saving chillers can not only reduce energy use, but also save costs in the long-term use of the process.
Consider factors such as the noise and appearance of the unit. For water chillers that need to be installed in public places, factors such as noise and appearance are important factors to consider.

In short, if you want to select a cost-effective chiller, there is no way to choose by yourself, you can contact our professional sales staff to assist in the selection.
