Carrying capacity of the air conditioner should mount a small air conditioner unit weight of less than 4 times 1) load. Carrying capacity of the air conditioner should mount a small air conditioner unit weight of less than four times. Mount bearing capacity outdoor unit at least not less than 180. Air conditioner outdoor woven material should not be loose mounting surface (such as the old house brick, hollow brick, etc.) Wall mounting; Gangan means limited conditions shall be used when the air conditioning technology wall installation Xuzhou transfer, promised minutes Consider installing surface of the material strength and the number of bearing endurance and installation of the air conditioner to a mounting surface of the element, take reinforcement or protective measures if necessary, in order to ensure safe operation and personal safety of the air conditioner. (2) lock. When the air conditioner is installed, connect its mounting surface and mount between the mounting bracket and the unit should be solid, stable and reliable, to ensure that the air conditioner installed does not slip, tip over or fall off. (3) rust. Steel mounting bracket and steel fasteners rust treatment should ask: air conditioning is quit under what circumstances except me? A: Exit defrost conditions: 1, the defrosting time is longer than 9 minutes. 2, defrost 4 minutes after the air conditioning recovery of waste in Xuzhou, inner coil temperature is greater than 0 degrees, and within 10 seconds in the coil temperature rises more than twice. 3, defrost for 5 minutes, the coil temperature is greater than or equal to 5 degrees. 4, the current transformer detects excessive current (relative to Guiji). Meet any of the above conditions is automatically exit defrosting state. Entry and exit defrosting process 1, enter defrost, immediately turn off the internal fans, compressors, external fan, 55 seconds to close the four-way valve, 60 seconds to open compressor. 2, exit defrosting. Turn off the compressor, open outside the fan, 55 seconds to open the advantages of a four-way home central air conditioning, home central air conditioning, also known as: residential central air conditioning. Is a small independent air-conditioning system in the cooling mode, the basic structure is very similar to the large central. The object is achieved by a host through a duct or hot and cold water pipes connected to the outlet ends of a plurality of cold, heating to different areas to enable multiple room temperature regulation, improve indoor air quality and the air conditioning disease prevention occurred. Second, the home central air conditioning advantages and characteristics compared with the currently used very widely split air-conditioning, home central air-conditioning technology content Xuzhou professional central air conditioning installation, have the advantage of a separate billing, compensation and other aspects of power. 1, the home central air conditioning seasons can run. Summer starts refrigeration unit to achieve cold adjustment; can be achieved with a heat source for heating in winter. The spring and autumn to effectively save energy can be directly air stalls. 2, compared to the traditional split air-conditioning, home central air conditioning can effectively control the supply air temperature, so that each room temperature uniformity. 3, home central air conditioner with a variety of air supply, consumers can develop different solutions depending on the room air conditions. 4, a logical addition to the new style, with bathroom, kitchen exhaust systems, to better ensure indoor hygiene requirements. The four seasons ventilation function is to meet the body's own health requirements. And these are far from ordinary split air-conditioning are not possible. 5, embedded, cassette, duct type, and a dozen styles to provide users with greater choice, can be better integrated with the interior decoration. 6. As a result of the modular host, you can automatically adjust the cooling capacity, and therefore energy saving home central air conditioning in outstanding performance. Consumers simply reasonable during the day and evening activities in the region according to personal habits were installed air conditioning, indoor and sub-control air-conditioning, the indoor and independently, separately adjust the air each region. 7, home central air conditioning installation uses a separate host and indoor installation, the overall air return air system design is reasonable, to provide consumers with a peaceful home environment. 8, easy to use and flexible. 9, when the home central air-conditioning in the heating operation state, not only to use central heating hot water, heat can be provided by installing a small wall-mounted gas heater as an energy source.
