mulit connected air conditioner - 7kw

1. Efficient, energy saving, environmental protection, traditional refrigeration conditions, the outdoor unit will heat into outdoor air, waste heat; three in one heat pump water heating technology under refrigeration conditions, the heat generated by the introduction of outdoor water tank insulation, on for free water heating, reduce the heat generated by the atmosphere, environmentally friendly and energy efficient. 2.R417A numerous environmental advantages of new environment-friendly refrigerant R417A refrigerant used in air conditioning water heater, with use of a number of advantages: stable performance, can directly replace the original R22, without replacing the compressor and expansion valve, and is compatible with MO, POE, PAG or AB compressor lubricants, great old and new products to facilitate post-sale repair; operating temperatures from a wide area in cold (-15 °C) above normal use; the water temperature can be higher than 70 °C, heating capacity; heating process, its high thermal efficiency than the R22, R22 to save more than 18% of energy; exhaust pressure, exhaust temperature is less than R22, compressor long life; by ASHRAE rigorous testing the toxicity and flammability rated A1 / A1 rating, absolute security. Protection function has a low, medium protection, sensor open or short circuit protection, over current, phase sequence, high pressure outside the feedback protection, frost protection water tank, self-test function. 3. Run economic data showed that: in the standard working conditions and to the family of five, for example, consumption of 50 liters per person per day 55 °C bath water calculated using the triple air conditioning central hot water than the ordinary electric machine water heaters, gas heaters save electricity 1040.25 yuan and 1,144.27 yuan (300 bath per person each year terms, price: 0.73 yuan / kWh, coal gas prices: 2.2 yuan / cubic meter); can provide cooling, heating air conditioning enjoy .
