Air conditioning general under the condition of high and low pressure is normal?
- This depends on the specific condition and the air conditioning refrigeration and heating of freon types, year-round operation under different indoor and outdoor temperature is not the same. Refrigerant R22, for example, if the cooling when outdoor temperature is 35, indoor temperature is 26, the air conditioning condensation temperature is about 50, corresponding to the high side pressure of 1.944 MPa, evaporation temperature of 6 degrees, corresponding to the low voltage side pressure of 0.6028 MPa. When heating, high and low pressure almost 1.3557 MPa and 0.5314 MPa.s
Household air conditioning cooling agent and machine outside or inside the machine, on her part
- Outside the machine, and the machine has a refrigeration of the valves
What kind of air conditioning the save electricity?
- Haier can also, but the brand is not the usual machine electricity savings, but to use correctly, the refrigeration temperature at 26 degrees, it is not hot nor cold, and don't put air conditioning in the near the sun can shine, close the doors and Windows during the day, try to pull a curtain, reduced sunlight can save a lot of electricitys
How to install home air conditioning (hang up) in the car
- Air conditioning not refrigeration, communication failures failure phenomenon: "run" the house lights flash (the rest) lights went out, inside and outside the machine doesn't work cause analysis: according to customer reflect, boot working properly, not present users reflect the situation, but after about 30 minutes, inside and outside the machine stops working, running lights flashing on the control panel, press any key air conditioning all have no reaction, unplug the power supply to commissioning, the machine can work normally, but after 30 minutes and appear the same fault, due to the downtime before air conditioning refrigeration normal, so the system will not exist problems, a preliminary judge for the external signal problems, from the company to provide fault display code can also be concluded that is communication, measuring signal cables inside and outside the machine is normal, so the external interference problem.s
Air conditioning energy consumption ratio is what mean
- Air-conditioning energy efficiency, is usually a household air conditioning can effect comparing (investigate) the appellation, is rated refrigerating capacity and the ratio of the rated power. In addition, changes in temperature type also includes heating household air conditioning can effect comparing (COP) this concept, refers to the ratio of the nominal heat and power rating. But, in terms of our country most of the regional air conditioning using habit, air conditioning heating is only an auxiliary means of winter heating, its main function is still summer cooling, so we usually call EER investigate, air-conditioning energy efficiency usually refers to the refrigeration of relevant national standards and to delimit the level of energy efficiency as the basis. In layman's terms, air-conditioning energy efficiency is to consume the same amount of electricity generated by the cooling/heating how many, the higher the energy efficiency of air conditioning, the province electricity. So, air-conditioning energy efficiency is one of the important parameters to measure air conditioning performance. Third, energy efficiency rating: At present domestic sales of air conditioning has ENERGY efficiency LABEL "" CHINA (CHINA ENERGY LABEL) of color LABEL, for the blue and white background color logo, divided into 1, 2, 3, a total of 3 levels, level 1 said products reached the international advanced level, most energy-saving, namely the lowest ENERGY consumption; Level 2 says more power saving; Level 3 said the energy efficiency for our country market average (old energy efficiency level is divided into 1-5 respectively represent different levels of energy efficiency).s
What is the working principle of household air conditioner?
- Household air conditioner has two parts: the commonly and the house. The indoor machine by motor, fan, condenser, mainly used for heat dissipation (in winter) or air conditioning (summer). Core: air-conditioners, including compressor, condenser, capillary and electronic valve, etc. Compressor is to compress refrigerant (freon) into high temperature and high pressure gas, through the condenser cooling, is what you said to exhaust, after capillary into normal pressure liquid at low temperature. Outside and inside machine exhaust heat just the opposite, and winter and summer switch is on electronic valve to control the direction of them.s
How long it will take air-conditioning on the right
- Air conditioning bring comfortable at the same time, also bring a kind of "disease". In the air conditioning work under the environment of learning for a long time, because the air circulation, not cannot get improvement environment, there will be a stuffy nose, dizziness, sneezing, tinnitus, fatigue, memory loss and other symptoms, as well as the related and skin allergic characteristics, such as skin firmness in dry, allergies, poor skin. This kind of phenomenon in the modern medicine is called "air conditioning syndrome" or "air-condition disease". To prevent air-condition disease, special remind home air conditioning users: don't open air conditioning, 24 hours a day in the evening or at work to close; 24 hours don't close the window; Don't too low, temperature and outdoor temperature difference not less than 7 ℃; Should often clean the carpet, bed sheets, sofa cover. For central air conditioning users, experts emphasize: response to hotels, restaurants, hospitals, bedding, appliances, curtain, etc to disinfection, often as far as possible let the sun. Supplement: for air-condition disease prevention, (1) use of disinfectants to kill microorganisms in air conditioning unit. Disinfectant can be repeatedly used, to prevent microbial regeneration. (2) because the humidity of air conditioner controller is fuelling the spread of bacteria tool, therefore, the need to increase the dehumidifier, in order to reduce the indoor relative humidity, so as to prevent bacterial growth. (3) after strenuous exercise, do not enter the air conditioning room, lest make open pores suddenly, so as to catch cold catch cold cause disease. (4) the air conditioning room and outdoor temperature disparity is bigger, so stay inside the bedroom shoulds not be long. Should make the skin the chance to sweat, water more, make pore unobstructed, to speed up the metabolism. (5) conditions, it is best to use the open systems model of the air conditioner, to maintain indoor air fresh, circulation.s
