During operation, the air conditioner produces a large amount of condensation liquid, which must be removed from the system and, accordingly, from the room. It is for this purpose that a device called a drainage pump or in other words a pump for an air conditioner has been created, which consists of the following structural elements:

a pallet compartment, produced condensate will accumulate in it;
a special drainage line along which condensation will be transported;
drainage air conditioner pump.

This article will discuss a separate element of the system, namely, we will tell you what is needed for drainage pump for air conditioner, its device and design.

Why do you need a pump for an air conditioner

drain pump for air conditioner

Absolutely all pumps are equipped with oversized pumps so that they can cope with the condensate of the air conditioner, which it produces during operation. Their productivity is indicated as - liters per hour. Also, when choosing a device, the following parameters are adhered to:

height of the water column;
noise effect during operation;
and other technical characteristics.

Purpose of the device

drain pump for air conditioner

Often, these pumps are used in case of breakdowns of air conditioners or their installation in specific conditions, where an additional pump is required to pump condensate.

As a rule, manufacturers complete their drainage pumps in advance, already the initial a pump for an air conditioner, thus, all the technical values and parameters of these devices already meet all the necessary conditions in order to provide the air conditioner with full functioning.

The drainage system itself must be installed next to the air conditioner in cases where there is a very long route along which condensate flows. After all, it happens when, due to the long path of the liquid, it is necessary to overcome the height differences, due to which there is a loss of pressure, and it simply does not flow out. The selection of a pump for drainage is based on the conditions of the environment in which it will be used. Below we will tell you about the types of drainage pumps.

Types and features of the drainage system

drainage pump features

All drainage pumps can be divided into several types, and each of them is designed to work in certain conditions:

Separate pumps - they are equipped with a small reservoir, which is equipped with a sensor to determine the level of the liquid inside. Thanks to their special structure, they can be mounted on drainage pipes, on the very drainage path, or inside the condensate compartments. However, the standard installation site is a separate special unit that connects to pallets or a two meter long flexible system tube.The performance indicator for these pumps ranges from 7 to 60 liters of fluid per hour. This value is sufficient for most modern air conditioner models. Subject to the conditions for correct installation, they are capable of pumping condensate to a height of 15 meters. However, they are not suitable for installation in specific operating conditions.
Pumps for filling options - equipped with capacious tanks, and there is no sensor in them that determines the water level. They have a higher capacity compared to the previous type, since their performance value starts at 80 liters per hour, and can reach up to 1500 liters. However, there is one drawback, they are not able to lift liquid to a great height, their maximum is about 7 meters. These systems are not intended for lifting liquid, since they were created to service external block multisplit systems, and the condensate passing through them goes directly to the sewer system.
Built-in pumps - they are installed in all standard cassette and duct split systems, as well as in air conditioners from famous manufacturers in this area. As for the performance value, it starts at 5 liters per hour, and the maximum reaches 165 liters. Designed for installation in specific conditions, except for those cases when the system requires an additional vacuum source to pump condensate.
Peristaltic pumps - designed to lift water to a height of 15 meters. The performance of these systems is very low, it is equal to 10 liters per hour. The downside is that they are overpriced compared to their counterparts. And systems with high power will also cost more than other counterparts.

System installation specifics

There are several ways to install the drain pump. However, it is not always needed, if the drain pipe is correctly installed and at the same time the inclined angle is maintained, then the condensate will flow by itself, then in this case the system is not needed. But this does not always work out, so a drainage pump for the air conditioner was made. With its help, it is possible to achieve all the necessary conditions in order to ensure free condensate, even if it is timely removed from the system.

Cons of drainage pumps

They mainly concern construction:

due to the fact that the systems are equipped with a small electric drive that brings the system into working condition, it can be somewhat noisy, which causes some discomfort to some owners;
for the drainage pump, free access is required, since it will be necessary to constantly clean the filters, which quickly become clogged due to the fact that condensate is generated and flowing out takes dust with it, and this is bad for the system, which can lead to deterioration in functioning or even breakdown.
