The power saving question very much is particularly acute for many owners of owner-occupied dwellings. Modern technologies allow to lower considerably costs of heating of the house and supply of hot water. The heat pump which mounting can be made the hands will provide free collecting energy from the environment.
The heat pump is the small device intended for heating of the building and supply of hot water. This installation differs in environmental friendliness therefore it is absolutely harmless not only to the person, but also to the environment.
Depending on season and operating conditions the heat pumps allow to reach the best efficiency of heat supply. The term of their service reaches 15 years. Installation of heat pumps pays off in three years, thanks to high efficiency.
What does the principle of operation of the heatpump consist in?
This system consists of the heat pump, the device of fence and distribution of heat. During creation of internal contour of the heatpump the compressor, the evaporator, throttle valve and the condenser is used. The electric power is necessary only in order that the compressor could work. Development of the principle of operation of the device has been made in the 19th century. Already then he has received the name "Carnot's cycle". Operation of the pump consists in the following: - in collector the supply of nonfreezing mix as which it is possible to use water with alcohol, hydrochloric solution or glycolic mix is made. Its task consists in absorption of heat energy with the subsequent transportation to the pump; - in the evaporator the energy passes to coolant therefore the last begins to boil, evaporating; as a result of pressure increment of the compressor temperature increases; - all heat energy is transmitted through the condenser to the heat carrier of the heating services placed indoors, at the same time coolant, being cooled, turns into liquid state and is restored to collector.
Advantages of use of heat pumps
Unlike standard sources of heat the heat pumps having high power have the mass of advantages from which It is necessary to distinguish: - high economy which is directly connected with lack of need of purchase, transportation, fuel storage; - economy of space which is required for installation of the boiler house, transport way and fuel warehouse. The inexpensive heat pump installed theto hands does not promote change of the general landscape of the territory and facade of the house. Besides, thanks to the compactness, the pump remains absolutely unnoticed for public eyes.
Types of modern heat pumps
There are several types of this installation: - device of open type; - the device of the closed type; - the equipment with the heat exchanger of horizontal type; - vertical heat exchangers.
Installation of the heat pump
Cost of the heat pump rather high. And it even if not to consider call of experts for its mounting. Not everyone is able to afford to spend the large sum, even taking into account that within three years the pump completely will pay for itself. It is possible to save if the thermal pump is established independently.
Before works it is necessary to make sure of serviceability of the electric counter. Especially it concerns those cases when installation of the pump is made in the house of old construction.
For this purpose it is necessary to make predesign and to make several deep wells. Their depth can vary ranging from 70 up to 150 mm. To exclude hit of underground waters on collector, before the beginning well-drilling it is necessary to make geological researches then to get permission from appropriate authorities. For mounting of the collector the earth is skimmed and installation of earth collector is made. After that the soil is put on the place. The heat pump is installed indoors.
Mounting of the heat pump does not need capital construction jobs therefore it can be hung up even on wall or roof of object.
Connection of the pump with wells and earth collector is carried out by means of two pipes. And connection it to the accumulative tank and to heating system happens in the same way, as to the air heat pump.
