If you're in the Big Apple, you might need to adjust your weekend schedule, because it's getting hot in herre.The National Weather Service issued an excessive heat warning Friday for New York City and the southern part of the state through 10 p.m. EDT Sunday. The service warned that heat index values — or how hot it feels outside — could reach 110 degrees on Saturday.CBS reported that at a news conference, Mayor Bill de Blasio warned the city, telling New Yorkers not to be outdoors this weekend unless they must be. Then he added a catch: He requested you chill out on your A/C usage. "The last thing any of us wants to go through is a blackout," de Blasio said. "If you set your air conditioner to 78 degrees, you’ll be fine, and you’ll help protect yourself and everybody else from the danger or a power outage."Now, 78 degrees may sound nowhere near the temperature you want your home to be in what the weather service is calling "oppressive heat and humidity." But it might not actually be such a crazy idea.

As noted in "The Building Environment: Active and Passive Control Systems" by Vaughn Bradshaw, the American Society of Heating and Air Conditioning Engineers' comfort standards states that "the preferred temperature range" for people wearing summer clothes is 73 to 79 degrees Fahrenheit.This is especially true if you're trying to save money on utilities: The U.S. Department of Energy explains that cranking the thermostat to be colder than normal "will not cool your home any faster and could result in excessive cooling and unnecessary expense."However, Consumer Reports notes that cooling rooms with window units, which are everywhere in New York City, may be a little harder. It recommends turning on the A/C to 78 degrees, waiting a while and adjusting accordingly.Don't forget you can keep yourself cool in other ways, like closing your blinds, drinking lots of water and using fans.Density of ice cream shops in New York | Enter ZIP Code for shipping options Frigidaire's FFRE1833S2 Energy Star 18,000 BTU 230-Volt Window-Mounted Median Air Conditioner is perfect for rooms up to 1,170 square feet.

Full 1 year warranty parts & labor Limited 2-5 year warranty-sealed systemAir Conditioner Controllers have evolved to become more advance in tandem with the advancement made in the field of microcomputer. These days, most window air conditioner and room air conditioner in your homes or offices have electronic controllers in them that make the units more user friendly, intelligent and feature-rich. See some of the typical air conditioner controllers functions or some slight variation depending on the manufacturers of your unit. The compressor is the most important component of a vapor compression refrigeration system. The ON/OFF type of compressor used to be popular in the past but DC Inverter type of compressor is the latest technology in the market though more costly.The ON/OFF compressor will totally ON or totally OFF depending on the set temperature and the ambient temperature. Usually there is a dead band of about 1.5 °C to 2.0 °C to prevent ON-OFF cycling of compressor that will reduce its lifespan.

In cooling mode, the compressor will turn ON when the ambient temperature of the room is higher than the set temperature by 0.75°C (different manufacturer will have different value). It will only go off when the room temperature drops below 1.25 °C (different manufacturer will have different value). An example of the operation of a compressor in cooling mode. The disadvantage of this type of compressor is that the temperature range of the space being cooled is too big causing discomfort to the occupants during the time the compressor is either ON or OFF. The other disadvantage is the starting current of easily few times of the steady state current every time the compressor starts.Control Of AC/DC Inverter CompressorThe DC Inverter or AC Inverter type of control (obviously the compressor will also be of DC or AC Inverter type) has better control in that it does not have to turn off totally. The frequency of the rotation of the compressor can vary depending on the load required.

Hence the room temperature of the space being cooled can be very close to the set temperature most of the time with some slight variation.This type of air conditioner controllers provides a more comfortable cooling to the occupants as the temperature is constant most of the time. It is also more energy efficient and environmental friendly as most of the refrigerant used is ozone-friendly. The disadvantage is this type of unit is higher cost compared to the ON/OFF type. The mode setting button at the remote control usually enables you to set the mode of operation. It  can be set to COOL mode, HEAT mode (if your unit is a heat pump unit), DRY mode, AUTO mode or FAN mode. Look at the manual provided to see the symbols of each mode.COOL mode is the default setting that you will use if you want to cool the room upon entering it. The air conditioner will regulate the temperature to achieve the setting temperature of your remote control. A temperature setting of 24 C° is a good setting to save energy.

HEAT mode is the mode that you will use when you need to heat up the room during winter. In this mode, the evaporator effectively becomes a condenser and vice versa by using a reversing valve to reverse the flow of the refrigerant. A temperature setting of 28 C° is a good setting to save energy.In heat pump model, AUTO mode is a mode that will automatically change the mode between COOL and HEAT by sensing the temperature in the room. If the room temperature is low, HEAT mode will operate and if it goes up to a certain temperature, it will switch to COOL mode.In air conditioning model and depending on the manufacturer, the AUTO mode is actually operating in COOL mode but with a lower set temperature to cool down the room quickly before reverting to the set temperature of the user.DRY mode is a variation of COOL mode where the compressor will cycle on and off (or low speed if inverter model) for a few minutes each depending on the temperature of the room. By this cycling, the moisture will be removed from the room hence the humidity of the room will drop.

This is basically a dehumidifying function.FAN mode exists in some model. This mode is hardly used as there is no cooling effect to the room. Only the indoor fan is on. Most air conditioner controllers have the built-in economy or sleep mode function. This function is used when one is going to sleep. When activated using the remote control, the air conditioner unit will raise the set temperature in steps after a period of time. This is because the required cooling will reduce when one sleeps.Depending on manufacturer, the set temperature could increase by 1 °C after 1 hour of operation, 1.5 °C after 1.5 hours of operation and 2.0 °C after 2 hours of operation. Use this mode to save energy.Usually the fan speed can be change to Low, Medium, High or Auto. The Auto mode has a built-in intelligent that determine the speed of the fan depending on the room temperature and set temperature. Higher speed is used if the difference between these two temperature is high and lower if low.Most unit will also have timers that you can use to ON or OFF the unit based on the clock of the remote control.

Some simpler unit does not have clock but has delay timers that allow you to set the number of hours elapsed before the unit is turn ON or OFF.The auto random restart is a feature that will retain the settings of the controls in the event of a power failure. Once power is restored, the air conditioner will restart to its last settings with the compressor being powered up randomly. This is a good feature to look out for before you purchase the unit.Ionizer is now a basic feature in most room air conditioner unit. It is located at the indoor unit and has a high voltage electronic module that ionized the surrounding air with negative ions. These ions will attract dust and other contaminants from the return air to ensure that only fresh and clean air is discharged from the fan coil unit. Take note that the module will have to be changed after a certain hours of operation to ensure its continuous efficiency.Air louver function helps to direct the air flow in the direction of your choice. Most controls have a least up and down control of the air.

Some units may have left and right louver control as well.See the troubleshooting guide of the printed circuit board of a split unit.Learn how this thermostat can be used to discharge hot air during winter and cool air during summer.See the wiring color code of a typical thermostat.See the electronic symbols that represent the various components that are used to control the air conditioning systems.Use the 7 Day Programmable Thermostat to schedule your air conditioner and save energy at the same time. Types of HVAC ThermostatBasic descriptions on the types of thermostat that are usually used in HVAC. See the simplified block diagram of the split air conditioner using the latest DC inverter technology.This is another networking technology that you can use to link up all your equipment. This Master/Slave serial communication was one of the earliest developed by Modicon. BacNetThis is one of the earliest standard communication protocol developed for building automation control including HVAC.
