heat pump-defrost cycle
Comments (20)"He didn't check the strips--just made it defrost and said it was kicking in according to the amps." - The 10 kw strips consist of two 5 kw sections. Only one 5kw section may be operating properly. Bad wire or bad sequencer. Get his a$$ back and have him meter the strips while the condenser is in defrost to make sure that all strips are energized. If you have 10kw strips and both are working fine, replace them with 15 kw strips (Goodman part# HKR-15C, approx $100). Did he check the air temperature after the strips to see if you were getting the 76 degrees that he stated? "The defrost is on 60 min. I need to change this to 90??" - Depending on climate and conditions, a longer defrost initiation time saves you money and helps with wear-n-tear on your system. I moved mine from 60 to 90 minutes with no problems with freeze-up, in Baltimore. FYI 10 kw electric strips provide an approximate 26 degree temperature rise at 1200 CFM fan speedd. If the air temp before the coil is 50 degrees, then the air temp after the coil is 50 + 26 = 76 degrees. If one of the 5 kw strips is not working, then 5 kw provides only a 13 degree rise, so 50 + 13 is 63 degrees. This will cool the house. 15kw strips provide a 40 degree rise in temperature.

Comments (13)Short cycling occurs when the AC has much more capacity than the heat load of the house. The AC turns on and cools the house very quickly. Quickly could mean 10 - 20 minutes. The short amount of time does not allow the AC to lower the indoor humidity. You feel cool but your are still sweating. It becomes a problem if you live in an area which has high humidity. The 5 ton capacity refers the size of the condenser. The blower in the air handler is adjusted to work with various condenser sizes. Your handler may be able to work with a smaller condenser. I don't have a good feeling about the installation contractor. He has done a poor installation and appears to be avoiding you. What type of warranty does he provide? Make sure you document the problems and stay on top of him....See Morerheem heat pump system - message on thermostat - check heat pump

Comments (9)Sizing a Heat Pump Pool Heater. https://www.heating-air-conditioning.org/ You should have a trained pool professional perform a proper sizing analysis for your specific swimming pool to determine pool heater size. Sizing a heat pump pool heater involves many factors. Basically, a heater is sized according to the surface area of the pool and the difference between the pool and the average air temperatures. Other factors also affect the heating load for outdoor pools, such as wind exposure, humidity levels, and cool night temperatures. Therefore, pools located in areas with higher average wind speeds at the pool surface, lower humidity, and cool nights will require a larger heater. Heat pump pool heaters are rated by Btu output and horsepower (hp). Standard sizes include 3.5 hp/75,000 Btu, 5 hp/100,000 Btu, and 6 hp/125,000 Btu. To calculate an approximate heater size for an outdoor swimming pool, follow these steps: Determine your desired swimming pool temperature. Determine the average temperature for the coldest month of pool use. Subtract the average temperature for the coldest month from the desired pool temperature. This will give you the temperature rise needed. Calculate the pool surface area in square feet. Use the following formula to determine the Btu/hour output requirement of the heater: Pool Area x Temperature Rise x 12 This formula is based on 1º to 1-1/4ºF temperature rise per hour and a 3-1/2 mile per hour average wind at the pool surface. For a 1-1/2ºF rise multiply by 1.5. For a 2ºF rise multiply by 2.0....See Morepl_1121
