Climatic equipment is presented on the market in different variations in terms of the functions performed. Traditional air conditioners mainly focus on air cooling in the summer, but as technology has developed, manufacturers have increased the lower bar of operating temperature. The split system for heating and cooling is especially effective as a universal climate control unit. In winter, it cannot be considered as a full-fledged heating equipment, but this option is quite suitable as a corrector for the indicators of the home microclimate.
Features of split systems
Unlike air conditioners, split systems are formed by two blocks, one of which remains in the room, and the second is carried out. But not every model of such a technique is suitable specifically for performing the heating function. Such modifications are usually equipped with special devices, including a pressure switch. Using this adjuster, the user can control the heating of the premises with a split system by controlling the frequency of the fan. Also, the installation can not do without a heating element, which complements the compressor crankcase. This device is usually supplied with a sensor, based on the values āāof which the system can perform automatic climate control.
A feature of the āwinterā split-systems is the presence of a heating element for heating the drainage. At minus temperatures, the drainage pipe may freeze, as a result of which water from the inner segment will pour into the room. Therefore, to prevent such situations, the split system for heating should be equipped with safety devices. They are not designed to provide warm flows in the room, but to fulfill the tasks of technological protection of communications of the air conditioner itself.
The main characteristics of a split system with heating
Like any climate equipment, split systems are primarily characterized by power. In this case, one should rely on the power potential of the indoor unit, which, depending on the design, can vary from 1.5 to 20 kW. Wall-mounted household models have a minimum indicator, and channel and floor-ceiling modifications usually demonstrate the maximum power value.
The next most important parameter denotes the temperature range with which the split system for heating in a particular design can work. On average, equipment control allows you to set the temperature from 16 to 30 Ā° C in the upper range. For comfortable operation, it will not be superfluous to pay attention to the noise figure. The indoor unit usually operates within 24-26 dB, but some modern models also show lower values āādue to the presence of effective noise isolation.
Operation of a split system in winter
The possibility of heating the room with air conditioning is not outlandish. However, most models, if they rely on this function, then in autumn and spring. In winter, heating is supported only by individual configurations of such plants. This is the first point to consider when starting up the unit at sub-zero outside temperatures.
Now you should answer the question of how to turn on the split system for heating at temperatures below -5 Ā° C. The fact is that this is a threshold value for the vast majority of models - it is not recommended to use the equipment beyond the specified temperature boundary even in cooling mode. But if the installation has a special kit for winter start-up, then it can be turned on even at -25 Ā° C. Electronics control is carried out in the same way as at high summer temperatures.
Maintenance of split systems
Before operating the equipment in conditions of negative temperatures, that is, in winter, several preparatory measures should be performed. First of all, you need to check the condition of the filters and, if necessary, clean or replace them. Next, antifreeze is checked. The efficiency of the system and its durability depend on its quality. If the split system for heating will not be used in the winter, then care should be taken to remove moisture from the heat exchanger. For this, the equipment must be put into fan operation for about 3 hours.
Heated split systems manufacturers
The leaders in the general segment of air conditioners are Mitsubishi, Toshiba and Daikin. Quite high-quality and functional equipment also goes under the LG and Panasonic brands, but it is the above-mentioned manufacturers that regularly offer users new opportunities, including supplying models with the heating option. Mitsubishi, for example, manufactures ergonomic split heating systems with an intelligent control system. Some modifications from this line are successfully integrated into the infrastructure of a smart home. As for Daikin and Toshiba, the developers of these companies are developing the technology in a structural sense, offering cost-effective solutions in the form of multifunctional systems.
How to choose a model for heating?
Still, you should rely on the form factor and connectivity when choosing in the first place. A suitable design will make it possible to install the equipment in a specific place - it can be a wall, floor, cassette or column model.
Next, power parameters are selected. As practice shows, 2.4 kW is enough for household services in a small room. Modern installations efficiently consume energy, which makes it possible to maximize the use of power output. For example, in the instructions on how to put the split system for heating, special modes of operation are increasingly noted. As a rule, these are optional operating programs in which the optimal settings for operating indicators are initially set with the expectation of external conditions and user requirements.
Conclusion
Universal and multitasking equipment with all the ease of use does not always please users with the quality of their functions. Especially when it comes to opposing tasks - cooling and heating. Nevertheless, expectations from such air conditioners are met by a significant part of users.
Firstly, the split system for heating a house in winter in terms of energy consumption does not exceed heating equipment. This means that you can count on savings in the operation of equipment. Secondly, such modifications of split systems precisely as temperature correctors show their best qualities. Of course, you should not count on the full operation of equipment for heating a house.
