Commercial Heat Pump
commercial hot water heat pump are a complete set of heating and cooling solutions that can provide your business with a year-round comfortable environment. Each model, regardless of efficiency level, is designed from the compressor to achieve quiet, efficient and long-lasting performance. And because the system is contained in an outdoor unit, it does not take up valuable indoor space. The heat pump split system can meet your heating and cooling needs and save money in the process. A heat pump is an air conditioner condenser that is configured to work "reversely" in winter when heat is required instead of cooling. You can get a heater and air conditioner in an efficient unit. We provide a wide range of air source heat pump options to ensure that your heating and cooling needs are met, and our most advanced products can save you a lot of electricity bills. Our heat pump inventory includes 230-volt and 460-volt installations ranging from 3 tons to 10 tons.
Large heat pumps are being used more and more for commercial and other non-domestic premises including schools, sports centres, shops and offices. It is estimated that around 40% of CO2 emissions can come from commercial heating alone and finding new and innovative ways to heat premises is at the top of the list for many businesses.
A heat pump delivers around 4 kWh of energy for every 1 kWh of electricity used to power it, which means they are 300 to 400% more efficient than electric heating alone. Whilst the cost of installing something like an Air Source Heat Pump will vary depending on the size and complexity of the commercial premises, there is no doubt that significant savings can be made.
A well-designed commercial heat pump is more than capable of providing all the heating needs for a business and, in the long term, represent good value for money in savings from reduced energy bills and the income generated from the Renewable Heat Incentive, as well as helping commercial premises bring down that all important carbon footprint.
Guangteng has been involved in a large number of different types of commercial projects for school, hotel, building projects, and so on. We had been entrusted to apply our heat pump expertise to design innovative solutions that meet the specific requirements of our clients.
technology
The heat pump operates in the same refrigeration cycle as any other traditional air conditioning system. The only difference is that the refrigerant circuit is equipped with a reversing valve, so the refrigerant cycle can be carried out in both directions. It can absorb heat from the space and discharge it to the outdoors. Or take the heat away from the outside and bring it inside.
Just as the fan rotates clockwise or counterclockwise according to the direction of rotation when the motor starts, the refrigerant coils don't care whether they are in evaporator mode or condenser mode. Either way, the system is efficient.
It is generally accepted that heat pumps are more complex than other systems. However, they only have two more moving parts than conventional refrigeration devices, and they have zero-maintenance electric coils for heating.
Application field
The only limitation on heat pumps is that when the external temperature drops below 45°F, the efficiency drops until the system usually shuts down below freezing and uses resistance coils as a heat source.
Unfortunately, electric heating is the most expensive method of heating a space. Only in a climate where the ambient temperature drops below the freezing point during the normal building operation time of the normal few days a year is justified.
This is not to say that heat pumps can only be used in temperate regions, because many buildings in the northern region must run air conditioning throughout the winter. These are usually large multi-storey buildings with large lighting equipment or human loads in the interior space (buildings that are not exposed to the outside through walls, roofs or floors).
The only living space that needs heating in winter is the outside area. The rest of the building needs to be cooled all year round. These areas can be easily repaired by a heat pump and may need to be preheated to prevent frost from forming on the outside coils when it is cold outside. This cycle only needs to run until the internal loads of the building begin to require cooling.
In any case, the exterior area of the building is usually served by a dedicated air handler, while the interior area is handled by other air handlers. Therefore, it is mechanically impractical to install a heat pump in the inner area, and it is mechanically impractical to install a conventional system with a gas stove in the outer area.
The advantages of using heat pumps for internal areas are simplicity, space and cost. The system is simple because there is no stove. A vacuum box with coils can be used to reheat conventional systems.
Therefore, a dual-pipe system is not necessary, and a mixing plenum is not required. Because the heat pump system has a small footprint, it can save a lot of ceiling space and floor space, all of which help reduce costs.
Accessories
In summer, a generally effective way to use heat pumps and winter cooling systems is to provide hot water.
This requires only a simple modification of the basic system to discharge the heat extracted from the building air into the water in the storage tank instead of into the air. The heat transfer efficiency with water is almost twice that of air, so you not only get free hot water, but also a more efficient cooling process.
Ingenious installation can make the heat pump evenly pass through the building, so no other main hot water source is needed.
The size and number of hot water pipes are greatly reduced with more local services, and the size and operating costs of pumps are also greatly reduced because hot water is always used relatively close to the water source.
So far, in cold climates, the idea is to use conventional systems for external areas and heat pumps for internal areas. However, owners do not like to mix equipment types because it will complicate maintenance and upkeep. Therefore, even in external areas with a high heating load in winter, the option of using a heat pump should be considered.
The simplest option is to use a heat pump-gas stove installation. The size of the furnace will be much smaller than the traditional system, because the heat pump can operate efficiently at temperatures as low as 45°. However, this is not a common combination of equipment, so it is not the best idea.
For buildings with a large external air load, such as schools, better options can be used. The outside air is usually processed at a single central location in order to extract some energy from the exhausted air. In this case, a large gas stove is the most energy-efficient solution.
The remaining building heating load outside the building is usually offset by the people and lighting in the classroom. Therefore, once the building reaches operating temperature in the morning, there is no real need to get more heat from the local air handler. Or at least it cannot effectively handle the heat load (i.e. above 45°). In fact, usually only the external air system can be used to complete the warm-up cycle of the entire area at a higher exhaust temperature.
For buildings with fewer internal heat sources, the full heat pump system will have to rely on reheating coils in the valve box, or if it can be justified in cost than hot water coils, it will rely on electric heating.
The ultimate alternative to all heat pump buildings we hope is to provide water source heat pumps for external areas.
The water source system removes/extracts heat from the water flowing in the closed fluid circuit. If anything, they are simpler and more reliable than air source systems because their operating temperature is higher, more constant, and cooler.
Typically, a small boiler and cooling tower will be required to service a group of air handlers in the external area. However, in large buildings with water source heat pumps everywhere, a well-designed fluid system can transport cold water from the outer area to the inner area, and vice versa, so smaller boilers and cooling towers are required.
Heat pump is an efficient and reliable technology, and other heating and cooling systems should be considered at the same time. Used in combination with other systems, they can greatly improve the efficiency of heating and cooling systems at a lower installation cost.
