Heat pumps are equipment that are designed for space heating. They are also capable of cooling a variety of objects. The main element of the above device is the compressor. Today are available in different versions. The parameters of the heat pump, of course, change.

What are the important features to note

The main parameters of the pumps primarily include thermal capacity. To measure it, usually in kW. Next, consider the consumption of electricity and the conversion factor. The unit has its own voltage and inrush current.

Additionally considered the volumetric flow in the heating circuit, which affects the residual pressure. The flow temperature may be different. The level of device noise is measured in dB and depends on the power unit. Dimensions hydraulic connections are also taken into account and will help with the installation. Outdoor unit heat pump has its own voltage. In some cases, can be installed two sets.

Opinion about the pumps with piston compressors

As a rule, piston heat pump owner reviews gets a positive because of the rather high power. It is recommended to install in big homes or just rooms for heating. Efficiency they are usually in the region of 95 %. From shortcomings it should be noted the high pressure at which the compressor is quite difficult to handle.

Supply from the mains independently. Run the pump they have you can do, and this is an advantage. In General, many models are very bulky. In this regard, their installation is quite problematic. The drive to use high speed motors will not work. This is largely due to the peculiarities of the connecting rod mechanism.

The total voltage control units located at 230 Hz. In General, inrush current without limiter is quite high. In the end, the volumetric flow in the heating circuit can reach up to 1100 liters per hour.

The advantages of using rotary models

Reviews for the heat pump (rotating) often related to the dimensions of the device. Many consumers like this type because of its compact size. It should be noted, that the mass is quite low. Connecting rod mechanism in this modification is absent. As a result, manufacturers have managed to significantly reduce the number of moving elements. All of this ultimately affected the performance of the unit. A pump of this type can serve the consumer for about 10 years.

Service they are picky, and this is a definite plus. Various valves in the system is missing, and the gas supply is carried out evenly. The disadvantages of pumps of this type, unfortunately, have. In the first place may be noted the high cost of goods compared to other devices. Also there are some problems with the heating element. In General, models are mostly produced with the low power. Thus, they are best suited to houses with a total area not exceeding 100 sq. m.

Screw pump prototypes

Is there any Happy owners of heat pumps? Discussion about this can continue indefinitely, but it is safe to say that the screw types aren't known for the simplicity of its design. Weight they in most cases, as the dimensions are quite modest. In operation they are not choosy and particular attention is not required.

In General, wear items are small due to the lack of friction in detail. They can be used in a variety of areas. Additionally, they are set as low-temperature refrigeration units. The limit of the pressure screw pumps very large. The two-phase compression means possible. The power consumption is 2 kW. The heat capacity of the unit in the first place depends on the setting of starting current. The control units typically are available with voltage not exceeding 230 V. the maximum frequency is around 50 Hz. The flow in the heating circuit, the maximum can reach 1000 liters per hour. The residual pressure of the screw pump in an average of 500 bar. The conversion factor in many models does not exceed 2 COP.

What are the advantages of vane pumps type

Choosing a heat pump, for or against the purchase, all you need to consider. This type from other devices is different even supply. Compressors have pumps installed plate class. To electric motors of the device can be connected directly. In this modification the valves are completely absent. As a result, many models can boast a good reversibility. Submission from the back-pressure network is stable. To create a vacuum vane pumps can be used.

The Disadvantages of these devices, unfortunately, also have. First and foremost customers notice the high sensitivity units. Dependsthis setting from the environment in which the device is being used. If there are a variety of mechanical impurities, the rotor may be broken. Wear of the edges of the plates occurs quite quickly, and this should be considered. In General, the efficiency of vane pumps is very low and does not exceed 50 %. The reason for this can safely be called the slow flow of liquid. This process occurs at special gates. The liquid is also along the edges of the plates.

What's New axial piston modifications

Data heat pumps user reviews are not too good, but the power devices have claimed a big. Design in General is very complicated and maintenance of pumps of this type are problematic. Directly the rotor Assembly is connected with the cylinder. Also axial-piston heat pumps user reviews are negative due to high friction forces.

All of the universal joints in the housing are mounted on the washers. In some cases they are not able to hold out for long. In the end may affect the motor device. Thrust axial piston compressors depends on the type of installed joints. Some manufacturers in this regard is not encouraging.

reviews for heat pumps

Reviews about radial piston pumps

A Radial piston-type heat pump of the positive experiences the owners are often cause. Rated power of these devices can reach up to 2 kW. Energy efficiency models still leaves much to be desired. Noise many modifications reaches 50 dB. The dimensions of the pumps of this type are very different. Primarily this is due to the weight of the compressor. The rate of drainage they have on average 0.8 gallons per hour. Operating temperature range of the unit depends on the manufacturer. Models with a small volume of gas charging is a big problem. Mainly this is due to the narrow roads. Typically, their diameter does not exceed 15 mm.

The distance between the bolts should also pay attention to, and normal is the measure of 470 mm. In this case, it is possible to hope for high structural strength. For home use this modification can be used, but in industry it is useless. Life is great, but the maximum temperature is quite low. We should also mention the branded products Nordis. It uses a completely unique technology "Daikin". In many models there are special active filters. As a result, the device is able to significantly lower the maximum frequency of 165 Hz.

Devices with dynamic compressors

Reviews of heat pumps with dynamic compressors, you can often hear the positive. Many consumers of this type attracts with its multifunctional units. Refrigerant circuit it is in the inner part of the device. The maximum flow temperature can reach 60 degrees. Humidity allowed different. In General, the devices are easy to use and cleaning is quite comfortable.

Well as reviews of heat pumps with dynamic compressors affect the heaters. As a rule, they are installed built-in type. For hot water they fit perfect. Connection to the pipeline can occur in several ways, and it was good. Dynamic pumps operate quietly and comfort of their work is quite high. With heaters these devices can be combined, however, much here depends on the manufacturer. The conversion factor, thanks to the compressor, is on top. Installation of equipment is very fast. Today in the market you can find many compact models. Of the shortcomings can be noted only a complex diagnosis.

What are the advantages of centrifugal pumps

Vane heat pump reviews real owners is not too good, because much depends on the weather conditions. In a humid environment it quickly breaks down, and this is a big drawback. Fans in many of the models are installed in a modulator integrated type. Valves this modification provides a three-way. Also blade heat pump reviews real owners gets a negative for a low power that only reaches 4 kW. Emergency defrost models available.

If we consider the trade mark "Term", they, as a rule, use a new technology's "Pro E". Sensors of temperature of external air they have very high quality. The expansion vessel in many models has a safety valve. For the supply line in the body of the device is the buffer capacity. As a result, the connection to the water heater may be obstructed.

Centrifugal modification: reviews and benefits

In order to establish home heating, the heat pump of centrifugal type is suitable bad. More rational to use it in the industrial sector, and it has certain reasons. The first thing to note is quite complex Assembly service. Its design is very bigand it has many elements that need lubrication.

Evaluative reviews of heat pumps of centrifugal type say that their compressors require periodic cleaning from dust. Much in this case depends on the environment in which you use the unit. Completely disassembled to diagnose the equipment is very difficult. The characteristics of this type of pumps is not very different from other samples. Electricity consumption had an average is 2.1 kW.

Feedback about the models with axial compressors

Axial heat pump reviews real owners has good and lately is very popular. Design it very simple and to choose a model with compact size - no problem. The conversion factor they have a maximum of up to 2 POPS. However, the performance is pretty good and the wear is acceptable. As a result of manufacturer, you can get a good guarantee.

Also the axial heat pump reviews real owners receives a positive indicator for the high inrush current which reaches a maximum of 16 A. the Residual pressure in turn is typically 1000 liters per hour. Most models are available with two indoor units. In the end, the noise from axial flow pumps is quite high. Dimensions are also very large, and weighing device is more than 150 kg, In this case it greatly complicates the installation of equipment on object.

Whether it Is necessary to choose pumps with turbochargers

This type is designed for extremely low temperatures. Most models can be found in the Nordic countries. The service life of the pumps is increased. The company "Daikin" in this respect is very successful. Heating compressors have devices available. Also, the owners say durable pallets. For best operation, the unit established a system of cold plasma. It represents a set of active filters that can purify the air from any contaminants.

The Refrigerant in many models "Daikin" used series "410A". According to experts, it is absolutely harmless to human health. The mode "Control" is able to please the owner with a stable job at a low frequency. In the result, it is possible to achieve significant reductions in electricity consumption. The volume pumps of this type are not distinguished from the above devices. At a distance of 10 meters on average they give 55 dB.

Voltage indoor unit is able to reach a maximum of 230 V. the Average thermal power unit of this type is 3 kW. Thus, the conversion factor of the model can reach up to 3 COP. In the end we can say that the above modification to the insulation of the house fits well and for sure many will like it.
