DC Air Conditioner/ Solar Air Conditioner

12,000 BTU DC Air Conditioner For Off-Grid Solar & Telecom Applications

If your power source is native 48VDC (or -48VDC) as part of a telecom or off-grid solar application, SuperEn DC48VFT-12 all-DC air conditioners are your most efficient cooling choice. DC48 air conditioners can substantially reduce power supply/generation costs and battery requirements. An all-DC system means you get the advantage of extreme high efficiency without the need for inverters.

The SuperEn DC48VFT-12 is a purpose-built DC powered air conditioner heat pump for native DC power. It's designed to conserve power, and operate reliably for many years without maintenance.

Our Anti-Corrosion technology protects circuit boards, condenser, evaporator, compressor, and fan motors from salt air corrosion.

The DC48VFT-12 is a variable capacity, variable speed, variable refrigerant flow unit. There is no other solar or DC air conditioner like it on the market.

 

How IT WORKS? DC VFT Air Conditioner Technology

DC48VFT-12 Air Conditioner Technology Background
It starts with the compressor which uses 95% of the power consumed by an air conditioner. In all ultra-high efficiency AC-powered mini-split units, household electricity enters the air conditioner and passes through a rectifier, a component that converts the incoming Alternating Current (AC) to Direct Current (DC). The DC current passes through a frequency driver which applies power to the motor. The frequency of the power determines the output of the motor, which can be digitally managed to precisely control the motors speed. Because DC power can be used more efficiently, all of the highest efficiency AC-powered heat pumps and air conditioners on the market use DC powered compressors.

In an off-grid solar configuration where an AC-powered air conditioner is running from inverted solar power, the power is actually being converted twice. First, the native DC power from solar panels is inverted to AC by the inverter, and then the power is immediately converted back to DC after entering the air conditioner. Sound wasteful? It is, requiring more solar panels and more batteries as a result.

A key difference with our system – the DC48VFT-12 unit skips all of these conversions and uses the DC power directly without conversion loss.

DC VFT Solution
In addition to avoiding the cost and power loss of an inverter, our system is engineered from the ground up for use with solar. Special electronics anticipate and smoothly handle voltage fluctuations of up to 38% without affecting the operation. In addition to the compressor and control circuits, all other electrical components are DC powered including high efficiency DC fan motors, DC valves & solenoids, etc. There are no inverters used inside the system.

The brushless DC compressor and fan motors we use provide a "soft-start" which means that the typical startup surge of an AC air conditioner running on an inverter is eliminated. A normal air conditioner will draw up to 500% more amps on startup, meaning that when running on an inverter, the inverter must be oversized accordingly. Oversized inverters are much less efficient. The DC motors and controls used in the DC48VFT-12 system not only avoid needing an inverter, they also minimize the surge or spike at time of startup. 


DC VFT Compressor

The system uses a VFT (Variable Frequency Technology) controller and frequency driver in conjunction with multiple sensors and an algorithmic control circuit to raise and lower the units capacity in real time based on conditions as they change. The VFT controller manages the compressor speed, refrigerant flow, fan speed, etc., which can all be precisely matched to the immediate cooling requirements. As the set-point is closely approached, the system will lower its capacity and power consumption, running at a very low energy draw as needed to maintain proper temperature rather than overshooting the set-point and then cycling on and off like a standard air conditioner. Not including the avoided DC to AC to DC power conversion losses, the VFT feature alone saves 30-40% compared to a standard air conditioner.

The DC48VFT-12 air conditioner uses a neodymium permanent-magnet Brushless Direct Current (BLDC) hermetically sealed motor and compressor with high performance windings, similar to the technology used in the worlds highest efficiency air conditioners. This particular compressor is made for us by the same manufacturer that makes high efficiency compressors for Fujitsu, Carrier, Toshiba, and LG.

Considering the high cost of solar panels and batteries, it is crucial in an off-grid solar situation to make the absolute best use of every watt of power. That's where the DC48VFT-12 air conditioner proves its value by operating with the lowest possible amount of DC power consumption.

Q:Household air conditioning how should maintain?
2, reduce air conditioning switch times: both ordinary air conditioning that decide frequency and frequency conversion air conditioning, should avoid frequent switch of air conditioning. 3, should take when using air conditioning remote control battery for a long time, to cut off the air conditioner power supply.
Q:Can air conditioning filter pm2.5
Can not when winter heating, summer cooling. Common household air conditioner indoor machine filter can filter the larger foreign body, filter filter itself is not the PM2.5 so tiny particles. But in summer air conditioning refrigeration operation time, the chance to generate condensate, indoor small particles in the air will be condensed water out of the outdoor.
Q:Beautiful home air conditioning hang machine shows P4 what mean?
P4: the temperature sensor is open circuit or short circuit, check: 1, check whether the sensor ontology quad is broken skin or fracture; If you have replaced; 2, check whether the sensor connection between ontology and the electric control main board is solid and reliable, and make adjustment if there is a problem, If 3, use multimeter detection sensor resistance, resistance to zero or infinity, explain for sensor fault; Otherwise can determine for indoor mainboard failure; Replace the motherboard sensor replacement sensors, mainboard failure. The experimental results show that more than three years had not been cleaned home wall-mounted air-conditioner its bacteria number 50 times mall central air conditioning; Less cleaning air conditioning, use a few years later will become an important source of PM2.5. Relevant professional bodies of urban household air-conditioning household survey found that 88% of the air conditioning heat sink bacteria, 84% of the total number of air conditioning heat sink mold, air conditioning cooling in the check out bacteria and nearly one hundred times. Cleaning air conditioning to master the correct way, don't just clean screen pack, cleaning heat sink. Due to the air conditioning heat sink sealed, only by the wet cloth to wipe, brush cleaning is invalid, should use the normal manufacturer production air conditioning disinfectant. If the heat sink on the rid of the dirt and germs, also can make air conditioning refrigeration effect is better
Q:What is the high pressure and low pressure air conditioning? How to measure?
High pressure compressor exhaust pressure Low pressure of the compressor suction pressure. Usually on the compressor suction and exhaust valve has a special interface, using fluoridated table joins can be measured If is home air conditioning is a little trouble, to see if there is any plunger valve, so, measurement is connected by fluorine list
Q:Household central air conditioning and hanging air conditioning quality comparison?
The central air conditioning is generally a machine supporting multiple machine. Ordinary is a holder. It's involved in a problem, if the outside of the central air conditioning machine is broken, also is a few machine within the whole. Went on a work alone, are not affected. Yituo many central air conditioner generally not small. More than 3 p. The requirement for high voltage wire diameter. Long line. Broken of the high cost of maintenance. Easy to damage. Went on a not easy bad, or fix it. Is not affected by the other.
Q:Air conditioning can generally use a few years?
Design service life for twenty years! Because of the environment is different, generally in 10 years or so.
Q:What is the difference between Marine air conditioning and home air conditioning?
Makes no difference to our company all the year round for the navy and the customs pack of household air conditioner, is the must prepare anti-corrosion outdoor, because all the year round will slowly corroded by seawater invasion to play outside casing, and rust prevention is to do well. The other is no need to be aware of. And power supply must pay attention to the good, the ship's power supply system and the household power supply system, power supply can be directly linked to the ship's electrician is responsible for it.
Q:Home air conditioning is not how to use, how long does it need to open it
No rules must be ok But you don't have air conditioning in time will be bad electronic products is always the same
Q:The fluorine plus air conditioning is what type?
To have a look at what type of air conditioning nameplate to mark refrigerants, and then add what models. At present commonly used R22, R410A, few have R407C, R410A and R407C belong to environmental protection refrigerants. If the nameplate of air conditioning can't see, can have a look at any specified on the compressor refrigerants. Don't mix.
Q:Air conditioning can not open 24 hours a day. Air conditioning will not bad ah
Air conditioning open 24 hours a day, air conditioning will certainly can not stand, easy to bad, good or not to open. In fact you practice is not desirable, in order to ventilation window, and then open air conditioning cooling. It is difficult to open the window air conditioning has effect, and is very inefficient. If for the sake of ventilation, again afraid hot, suggest you still such hot noon time open air conditioning, close the Windows open air conditioning, wait until the evening not so hot in the window, open the window, do not have air conditioning
